2	''The good news is, we can visit other Earths.'' \
3	''The bad news is, somebody out there doesn't like us.''
4
5	Something that looks like TimeTravel combined with [[AlternateUniverse alternative world]] hopping. ''GURPS: Infinite Worlds'' is the default TabletopGame/{{GURPS}} 4th edition setting, loosely inspired by Creator/HBeamPiper's "Literature/{{Paratime}}" novels. The successor to the Third Edition sourcebook ''GURPS Time Travel'' and its supplement ''TabletopGame/GURPSAlternateEarths''. The setting is detailed briefly in the GURPS core rules and at more length in the book ''GURPS Infinite Worlds'' and a couple of short PDF supplements, with brief passages in other GURPS supplements providing yet more ideas -- it's always easy enough to outline another timeline idea linked to a new book's theme.
6
7	The basic concept is this: A Parallel Earth (that calls itself "Homeline") develops the technology for travel to other timelines. It is controlled by the UsefulNotes/UnitedNations, which effectively becomes a World Government (an opinion not every nation and corporation agrees with). They secretly explore and exploit the other Earths (in ''relatively'' benign ways - buying resources from Earths that have plenty, for example, and dumping wastes on Earths that never developed life) and forms an organization known as "The Infinity Patrol" for the purpose of keeping "The Secret" (that is, the existence of TheMultiverse as well as the fact that you can travel to other worlds by technological means) from those Worlds that do not know about it (the vast majority discovered so far).
8
9	The reason is twofold. First, worldlines that learn The Secret may either be aggressive timelines, or become the victim of one, creating another reality-hopping danger. But the second deals with "echo" timelines that mirror Earth's past -- changing an echo by interfering too much may cause that reality to "shift" closer or farther away from Homeline (that is, it becomes more or less easy to access.) In fact, Homeline's biggest rival, Centrum, a World that also has "cross-time" technology but with a [[strike:Communist-type]] socialist technocratic society, seeks to draw worlds "closer" to themselves so they can influence them into developing similar governments. Occasionally, "outtimers" (slang for people from outside Homeline) are recruited to join Infinity if they are judged worthy. This is similar to a TimePolice setting genre except it involves parallel worlds instead of the actual past or future. (The book also includes a separate, Time Travel setting called "Project Timepiece" as well as settings such as The Order of the Hourglass, a pulp setting where adventurers [[MentalTimeTravel travel through time via their minds]].)
10
11	Oh, by the way there's a third up-and-coming player in the multiverse that recently extracted The Secret from a crashed Homeline conveyor. Homeline's name for their timeline? [[StupidJetpackHitler Reich-]][[OhCrap 5]].
12
13	This setup allows GURPS game masters to permit {{Crossover}}s between different genres. For example, the Earth of "IST" from the original ''TabletopGame/GURPSSupers'' has been recently discovered, which could allow for crossovers between the two settings. This also gives both the player and GM a huge sandbox to play with. This is to some degree, the purpose of the setting, as it literally allows the game master and the players to goof around, err... that is police the infinite multiverse where literally anything is possible (that includes some very weird possibilities) without worrying about actual time-travel (unless you want to, of course) The sheer complexity and size of the multiverse and the parachronic physics is probably the main reason The Secret can be maintained with any success at all.
14

For one setting within the Infinite Worlds framework that has received its own separate treatment, see ''TabletopGame/GURPSInfiniteWorldsBritannica6''; other, shorter PDF supplements have been published to provide a little more detail on other timelines.

18	----
19	!!This, as a setting for TabletopGame/{{GURPS}}, shares many tropes with TabletopGame/{{GURPS}}.
20
21	!! '''Other tropes''':
22	* AdventureFriendlyWorld: While the setting as a whole can be considered this, especially due to the focus being on parallel world-hopping adventures on, well, [[TitleDrop infinite worlds]], special mention must be given to the Cyrano timeline, which is basically what happens when you mix Creator/AlexandreDumas-style swashbuckling adventures, PlanetaryRomance, Franchise/StarWars, and ComicStrip/BuckRogers... then throw in a jumbo-size WeirdnessMagnet. Infinity has literally given up sending standard Patrol teams there; only ISWAT personel are considered badass and/or crazy enough to succeed missions there within acceptable parameters.
23	* AlienNonInterferenceClause: There's no general bar, but Infinity enforces individual ones for individual worlds. TheMasquerade needs to be upheld on ''all'' worlds, travel to worlds with advanced technology (in other words, potentially able to develop parachronics) is restricted, and cultural contamination, cargo cults and colonialism are to be avoided. Also, meddling with "echo" worlds (worlds identical to time periods in Homeline's past) is forbidden, but that's because their temporal physics are unstable. Other than that, trade and "benevolent guidance" happen all the time.
24	* AlienSpaceBats:
25	** Centrum and Homeline do a ''LOT'' of this, as often as not as a part of their ongoing conflict. Centrum promotes an ideology of a meritocratic, rationalist OneWorldOrder in more advanced worlds, or outright colonization of more primitive timelines. Infinity is less picky; they largely want trading partners for White Star, "benevolent guidance" in favor of peace and human rights, and most importantly to keep anyone else from developing parachronics.
26	** More worryingly, it seems that they may not be the only ones who do this, as the no less than 18 Gothas (parallels that all suffered a ZombieApocalypse with a common source) seem to point to [[MysticalPlague a common origin]]. On a (somewhat) lighter note, the sheer amount of InSpiteOfANail in the Ezcalli timeline, despite the divergence point (Phoenicians accidentally discovering the Americas circa 1000 BC, natch), has many people in Infinity suspecting it's also happening there.
27	** Infinity suspects that something's meddling with Campbell. Science isn't just dead in America and Britain (where an anti-technological religiosity has become the norm) but in the Communist powers (which share none of the West's technophobia) as well, and Patrolmen are smelling a conspiracy.
28	* ALighterShadeOfBlack:
29	** On Gotha-Z, the one major power that has not been destroyed by the G-Z virus is UsefulNotes/ImperialJapan. It's not any nicer than Homeline's version, and they make no bones about raiding non-Japanese survivors for resources, but given the fact that it's a ZombieApocalypse, Infinity isn't objecting too hard to the support they get from Homeline's Japan.
30	** On [[TabletopGame/GURPSReignOfSteel Steel]], Centrum's imperialistic Interworld Service can be considered entirely good guys compared to the the genocidal AI zoneminds.
31	* AllohistoricalAllusion:
32	** There is a mercenary outfit called Alternate Outcomes Inc. that works as the only PMC allowed to carry out out-time operations. The first PMC was [[UsefulNotes/SouthAfrica South African]] Executive Outcomes.
33	** A sidebar mentions how Infinity knocked off an al-Qaeda terror plot in early 2001. Merlin's CIA took out a similar group in Afghanistan in 2000.
34	* AlternateHistory: The point of the exercise, most of the time.
35	* AlternateHistoryDinosaurSurvival: The United States of Lizardia has dinosaur-descended LizardFolk with a society peculiarly similar to our own. (It may fall into an accessible quantum band because of psychic resonance effects linked to this.) There are also worlds with more straightforward dinosaur survivals, serving as interesting if dangerous destinations for research and tourism.
36	* AlternateHistoryWank:
37	** On Homeline, the biggest winner from the parachronic boom has been the US, which maintains the degree of world leadership that it had in TheNineties (in part because UsefulNotes/TheWarOnTerror never happened). There's also indications that France is becoming an aggressive crosstime rival to the US (and to Infinity). Russia is also a major player, due to giving its oligarchs access to the biggest resource boom in the Infinite Worlds.
38	** Any time the British Empire is doing too well in Quantum 6 and 7, it's a reasonable assumption that Centrum is involved; it's their favorite power to wank up high for cultural (they're descended from the Australian remnant of a global Anglo-French Empire -- although they would deny this has any relevence, as their whole world is equally Centrum), linguistic (they speak English) and strategic reasons (it's a very strong model on which to build a OneWorldOrder and easily guided along technocratic lines).
39	** In fact, this happens often enough that many alternate timeline designations are used specifically for timelines where a particular nation/concept was wanked.
40	* AlternateUniverse: Where all these alternate histories (and some worlds so weird they're barely recognizable as Earth) can exist.
41	* AncientConspiracy: The Cabal, which since it's mostly made up of sorcerers and assorted supernaturals with amoral, inscrutable ([[WeAreStrugglingTogether and often conflicting]]) goals, [[MagicVersusScience is an unwelcome wild card in the conflict between techno-centric Homeline and Centrum]]. [[StrawVulcan Centrum especially]], as their ingrained pragmatism and logic has a hard time coping with a concept as irrational as magic (they tend to pretend it's not there until it goes away, get rid of it by any means necessary if it doesn't, or [[ScrewThisImOuttaHere just pull out]] if neither option works).
42	* AncientEgypt: The mini-supplement ''[[https://www.sjgames.com/gurps/books/osirisworlds/ The Osiris Worlds]]'' details a few timelines with divergence points or interesting features in Egypt.
43	* AncientRome: One of the most common divergence points is a surviving (or resurgent) Roman Empire.
44	* AntiVillain: Centrum really isn't evil, just with [[BlueAndOrangeMorality alien social values]] (what we might term "ruthlessness", they term "practicality"). There's a section explicitly allowing the GM to decide if they should be ALighterShadeOfGrey or ADarkerShadeOfGrey, and another that mentions the possibility of an EnemyMine with Infinity to fight Reich-5 if it ever becomes a major player.
45	* ApocalypseHow: On Homeline, the year 535 was a Global/Societal Disruption; an eruption of Krakatoa led to a volcanic winter, ruining civilization around the world for a century.[[note]]OTL, there was indeed a year-long global winter in 535-536, and it may have had a volcanic origin, but its relation to collapsing civilizations around the world over the next century is contested.[[/note]] This event is also the most powerful reality quake zone known to Paralabs, and it's theorized that the quake actually took out an entire timeline and shook up all realities between 410 and 660 AD.
46	* ArabianNightsDays:
47	** Caliph twists this. It's a world mostly covered by Islamic nations in the 1600s, except that the magic is technological... and the worldline is by far the most advanced of any that either Infinity or Centrum have ever discovered.
48	** A more classical example is Burton, an anachronistic myth parallel that exists in a StableTimeLoop that coincides with the reign of Caliph Harun al-Rashid where the folktales are true.
49	* ArbitrarySkepticism: At Paralabs, magic gets this, specifically in contrast to PsychicPowers. While psionics don't usually develop on Homeline, they nonetheless fully fit into a "scientific" paradigm, and as a result, psionics is considered bleeding-edge science that everyone wants a piece of. Magic, by contrast, is seen as [[HowUnscientific unscientific]] by Paralabs, and the Sheldrake Section (who research such phenomena and developed the "mana level" classification) are generally seen as kookballs even in [[MadScientist Paralabs]]. The fact that Sheldrake Section insists on trying to fit magic into a predefined theory similar to [[Franchise/StarWars the Force]] isn't helping things, but nobody wants to be the one who admits that they believe in actual magic. (Veteran Patrolmen [[SeenItAll rarely share this prejudice]].)
50	* AwakeningTheSleepingGiant: There are several sleeping titans in this setting:
51	** Reich-5 was originally presented as a sleeping giant, but while it's awakened, it suffered DiminishingVillainThreat between its initial presentation and the exposure of parachronics, and the latter event occurred in such a way that most of the Nazi hierarchy is unaware of the situation, so the Armanen and Raven Division are more of a GoldfishPoopGang right now than a match for Homeline or Centrum. However, they're still very nasty, and if their superiors ''did'' find out what's going on...
52	** Merlin's another partially-awakened giant: a world with technology equal to that of our own Earth, but with access to advanced {{Magitek}} as well (in fact, the world of the ''TabletopGame/GURPSTechnomancer'' supplement). A blunder with Gate magic and Infinity's response to it made America's CIA aware of parachronics, and they've started spying on Homeline back (though Homeline is as of yet unaware of this); however, they are not necessarily hostile. More worryingly, [[ArgentinaIsNaziland the Condor Group Nazis in control of Argentina]] have made an alliance with Reich-5's Armanen.
53	** Caliph is a mostly-peaceful world of Islamic CrystalSpiresAndTogas, but its technology is centuries ahead of anything that Infinity and Centrum have, and both sides want it. Of course, any intrusion risks telling Caliph about the existence of parachronics, and that centuries-advanced technology makes Caliph into quite possibly the most powerful single worldline in existence. Both sides tread very carefully to make sure they don't accidentally let this djinn out of its bottle.
54	** Most horrifying of all possibilities is Shikaku-mon. A dark, overpopulated {{Cyberpunk}} world where democracy never happened, over half of which is ruled by an UsefulNotes/ImperialJapan that christianized and modernized early on, it would be a likely threat to Homeline for that alone. What makes it worse, though, is that parachronic projectors may work on that worldline, meaning that [[ParanoiaFuel if they develop parachronic technology, they can reach Homeline]]. Also, because it was discovered by a Japanese research team, Infinity were ''not'' able to keep the existence of Shikaku-mon a secret on Homeline, so it may be only a matter of time before the {{Masquerade}} breaks on this world as well. Sweet dreams!
55	** The ''[[https://www.sjgames.com/gurps/books/worldsofhorror/ Worlds of Horror]]'' supplement introduces another Sleeping Giant that is potentially far, '''''far''''' worse: Taft-1. Both Infinity and Centrum think that the point of divergence is Truman's early death and the election of Robert A. Taft in 1948. [[Franchise/CthulhuMythos It's]] [[CosmicHorrorStory not]]. And Merlin, mentioned above, also blissfully unaware of this, [[MuggingTheMonster is poking it with a stick]].
56	* BackgroundMagicField:
57	** The Sheldrake Section at Paralabs believe that every living thing generates a "morphogenetic field" that can be altered to reshape reality, and this is what various timelines call "magic." The theory's truth value is somewhere between "incomplete" and "bogus," but nobody wants to point at the elephant in the room and say they believe in actual magic.
58	** Scientists on Merlin have come up with their own understanding of magic that superficially looks like this, [[SubvertedTrope but isn't]]. According to Merlin thaumatologists, magic involves shifting physical laws from one dimension to another. Mana level isn't determined by the strength of the mana field (though "oz particles" that serve as a bridge between universes are a part of the theory) but by the weakness of the dimensional barriers in an area. Merlin seems to be closer to the truth than the Sheldrake Section, but their theory is also far from complete.
59	* BewareOfHitchhikingGhosts: A double inversion. Troubled people might get picked up by a mysterious stranger who gives them life-affirming advice before dropping them off. Turns out he's some kind of supernatural being (not necessarily a ghost) who drives across worlds for this very purpose.
60	* BlackAndGrayMorality: In Reich-2, the Western democracies of the US and UK are heavy-handed neocolonial and colonial overlords with authoritarian and racist tendencies, but the Infinity Patrol holds its nose and supports them against [[ThoseWackyNazis the Reich]], [[DirtyCommies the Soviet Union]] and UsefulNotes/ImperialJapan, who are all far worse.
61	* BrainwashingForTheGreaterGood: One theory about Siva-1 is that the pacifistic Jain psi-monks there have mind-controlled the world into accepting their message of nonviolence, ensuring that there hasn't been a war in over a millennium.
62	* BrokenMasquerade:
63	** The wheels are starting to come off in Quantum 3. Reich-5 is out of the bottle (though their parachronics are limited both to a GovernmentConspiracy within the declining Reich and more limited methods than Homeline and Centrum's) and has begun invading other worlds, while due to the emergency circumstances of first penetration, Merlin's U.S. government has discovered Infinity and is in the process of trying to infiltrate Homeline back.
64	** On Nergal, Infinity ''intentionally'' ripped up the Secret, reasoning that they couldn't develop parachronics and that a world built on slavery and HumanSacrifice could use a lot more "benevolent guidance" than normal. They're GivingRadioToTheRomans in southern Africa under a GodGuise.
65	** A more humorous example is Johnson's Rome. It was originally "just" a world in which the Roman Empire (founded by victorious Mark Anthony and Cleopatra) never fell and remained powerful (if decadent) until 1192 AD. That's when Alex A. Johnson, a small-time businessman from Homeland, arrived on a randomly dialed timeline, looked around, and openly breached the masquerade to... start a tourist resort, along with a hefty dose of (including literally) GivingRadioToTheRomans. By the time ISWAT figured out what Johnson Crosstime Incorporated was up to with their ostensibly "time travel to the Roman Empire" tourist venture, the timeline was changed so drastically and so thoroughly that it was too late to do anything about it. An average Roman citizen doesn't know where the "Jonsonus' visitors" are coming from, but they don't mind all the tech and money that keep popping out from the "barbarian" tourists.
66	* ButNotTooForeign: Done deliberately as part of the rules and fitting into the lore of the setting. The goal of parachronics is to first and foremost establish connection with ''close'' parallels. Thus whenever tables are used for rolling a random world, the most common outcome is a mid-to-late 20th century world with dominant Western culture, ruled by some sort of oligarchy. Anything outside that is going to be significantly rarer and it's by design near impossible to simply roll a world that goes beyond relatively mundane things in tune of "US-Italy Cold War during Rockefeller's presidency". Of course, nothing prevents [=GMs=] from ''manually'' making their own Phoenician discovery of Americas or 2nd Mongolian Empire stretching from ocean to ocean thanks to TheTunguskaEvent.
67	* CanonWelding: The 4e version of the setting has absorbed several campaigns from the 3e Time Travel book that were originally entirely separate settings.
68	** In a more general sense, just about every other GURPS setting has a corresponding world mentioned in the book. Including the licensed ones (yes, Infinity agents can visit Literature/{{Discworld}}, [[Franchise/ConanTheBarbarian Hyboria]] and Literature/WitchWorld). From a meta perspective, the ''Infinite Worlds'' setting basically exists to facilitate {{Massive Multiplayer Crossover}}s.
69	** On [[TabletopGame/GURPSReignOfSteel Steel]], [[spoiler: [[LaResistance VIRUS]] is actually a front for Centrum's Interworld Service.]]
70	* ChummyCommies:
71	** The pre-Soviet Communist movement plays with this. They're especially chummy by ''Centran'' standards, as a world-spanning socialist state is a meme that the TotalitarianUtilitarian technocrats can get behind. On the other hand, part of the reason is that they aren't tied to Soviet imperialism, which is [[DirtyCommies the bad kind of communism]] by the standards of ''both'' interworld powers.
72	** On Lenin-5, General Georgy Zhukov has denounced Bukharinism[[note]]Bukharin took the place of Stalin in this timeline, the main difference being that he didn't purge the Red Army[[/note]], ended the Soviet gulags, and is quickly becoming an ally of the West against Maoist China.
73	** Strangely enough, the Dixie-1 USSR is also this, being a democratic two-party Socialist welfare state with a prosperous economy and tech industry whose foreign policy boils down to "whatever inconveniences UsefulNotes/ImperialGermany (which is still an authoritarian imperialist regime fond of mass executions of rebels in its colonies) in the most".
74	* CosmicHorrorStory: There's hints of this in the margins. In particular, [[spoiler: the power of the Franchise/CthulhuMythos not only transcends time and space, but local physical laws. Azathoth's power can be called on ''anywhere'', even mana-dead worlds]]. This has disturbing implications for the Infinite Worlds, to say the least. And anyone who's read ''GURPS Cabal'' knows that their interpretation of reality both isn't much kinder, and is likely much closer to the true nature of things than any scientific paradigm.
75	* CrapsackWorld: Not as bad as most other cases and not immediately apparent, but the more you read, the more obvious it is that there are a LOT more crappy parallel worlds than reasonably nice ones (from the [[ColonyDrop Lucifer parallels]] to the [[StupidJetpackHitler Reich parallels]], with the disturbingly common [[ZombieApocalypse Gotha parallels]] and many others in-between), and even the nice ones tend to have ugly caveats -- Gernsback, for example, has world peace under the League of Nations (both TheGreatDepression and UsefulNotes/WorldWarTwo were averted) and awesome RaygunGothic SchizoTech thanks to UsefulNotes/NikolaTesla's inventions, but due to not having had those experiences, racism, sexism and colonialism are still firmly entrenched at pre-1940's levels in most inhabitants' minds. It still is one of the most positive parallels overall.
76	** Nergal, where the Assyrian Empire destroyed the Hebrews and Phoenicians, prevented the rise of Persia and set a very bloody standard for every empire to follow. Nearly every local culture practices human sacrifice, paper and alphabetic writing disappeared from history, and the world is slowly descending into an anomalous Ice Age that's hinted to be a result of dark magic. It's bad enough that Infinity has decided to throw TheMasquerade to the wind; Nergal lacks the technology to replicate parachronics, and to quote the book, "frankly, the Patrol would like to cause as much cultural contamination here as possible."
77	** It's downplayed, but Centrum's backstory has it arising from the ashes of a world war between megalomaniacal empires that [[WorldWarThree escalated beyond control]], destroying civilization except for a small colony of technocrats who resolved never to let that happen again.
78	* CrossoverCosmology: The book suggests that echoes exist for many, if not all fictional works (at the GM's discretion). A throwaway line mentions the existence of the [[Literature/LandOfOz Land of Oz]] on one alternate world and there's mention of a world where Literature/SherlockHolmes actually existed, but he was KilledOffForReal at Reichenbach.
79	* DeathWorld: Several parallels qualify, even appart from the aforementioned Gotha and Lucifer parallels, many of them colloquially called [[NamesToRunAwayFromReallyFast Hell Worlds]]. The causes run the gamut from [[DepopulationBomb incredibly deadly]] [[ThePlague epidemics]] to [[GreenAesop man-made ecological meltdown]] to [[NukeEm nuclear war]] to [[AlienInvasion Alien]] [[{{Ultraterrestrials}} (or maybe not)]] [[AlienInvasion Invasion]], but probably the most worrisome (i.e. most likely to be completely and irreversibly quarantined) are the (thankfully few) parallels that seem to exist in a CosmicHorrorStory universe. One of these parallels may have the [[EldritchAbomination Things]] back-tracing the parachronic trail from a Homeline Scout team.
80	* DecadentCourt: There are plenty around, of course. For example, on Cyrano, there's the court of Louis XXV. The manipulations of corrupt nobles and the mysterious Voice of the Phantom are leading France Outremonde to ruin, and even the King himself is either a pawn of or a collaborator with evil.
81	-->''To the new order, a man of honor was a threat to be crushed.''
82	* {{Demonization}}: A literal example in Azoth-7. When the Spanish Inquisition unexpectedly managed to summon Spain's tutelary angel to prevent an English invasion, the English accused them of making a pact with [[DemonLordsAndArchdevils Samael]] instead. This is ''probably'' not true.
83	* DidntSeeThatComing: Infinity completely missed a trick on Roma Aeterna. Infinity's intelligence indicated that Centrum would probably have to deal with their usual issue of only speaking English natively, which would make it harder to penetrate Roman society. ''That'' was incorrect; while English is the only living language on Centrum, [[https://en.wikipedia.org/wiki/Classics classical studies]] never quite lost their central place in education like they did on Homeline, meaning Centrum on the whole did a ''much'' better job blending in. As a result, Centrum has infiltrated Rome much more thoroughly than Infinity expected. Consequently, Infinity is both scrambling to regroup in that parallel, and being '''much''' more watchful in any other Roman/Greek-dominant world.
84	* DiminishingVillainThreat:
85	** In ''Alternate Earths'', Reich-5's Imperial Japan, especially their ''[[SecretPolice Kempei Tai]]'' organization, were every bit as deadly an adversary as the Nazis. In ''Infinite Worlds'', Japan is decaying into warlord states and the ''Kempei Tai'' have, within a single generation, gone from being the guys who gave the Gestapo nightmares to a bureaucratic tar pit.
86	** The Reich itself plays with this; while the Nazi regime is no longer the unstoppable Orwellian terror that it used to be, a faction within the decaying Reich [[OhCrap now has world-jumpers at their disposal]].
87	* DirtyCommies: In the Infinite Worlds, most forms of Communism are a very bad thing, driving several worlds directly into Hell or worse. The worst is unarguably [[spoiler: the "Worlds of Horror" supplement's Taft-1 USSR, where after discovering ''something'' in the aftermath of TheTunguskaEvent, Joseph Stalin "[[Franchise/CthulhuMythos signed his name in the Book of Azathoth]]" and the Soviets are actively meddling in ThingsManWasNotMeantToKnow]].
88	* DirtyCop: {{Downplayed}}. Serious corruption and empire-building in Infinity Unlimited are rare and structurally discouraged, and being on double payroll even rarer, but Patrolmen ''love'' smuggling undeclared goods to and from Homeline. Usually it's personal stuff like wine and souvenirs, or steel knives to trade offworld, though.
89	* DividedStatesOfAmerica:
90	** The Dixie parallels, where [[UsefulNotes/TheAmericanCivilWar the South won its independence]].
91	** On Gallatin, Alexander Hamilton died before he could write the ''Federalist Papers'', and New York refused to ratify the Constitution. America splintered, and now the United States of America is one of many American republics.
92	* DoingInTheScientist: Some of the nuttier sorts at Paralabs think that parachronics ''actually'' runs on ClapYourHandsIfYouBelieve. This hasn't been proven either way, owing to the one field test disappearing into thin air.
93	* DoingInTheWizard: Inverted, as there are several parallels where magic clearly exists, making it kinda hard to deny (though Centrum tries). There is even a loose group of powerful magic-users and monsters that also travel through realities, the Cabal (from ''Gurps Cabal'', natch). ''However'', the Merlin parallels play this straight by providing a scientific explanation for GURPS' default magic system, which is heavily tied in with parachronic travel itself.
94	* EnemyMine:
95	** One suggestion in the book is that Infinity and Centrum could ally against Reich-5. On the other hand, a vignette in the book suggests that Centrum might take advantage of Homeline's fixation on "the Irrationalist sect from Bavaria" to draw off Infinity resources.
96	** Averted on Steel. Both Infinity and Centrum agree that the [[MasterComputer zoneminds]] have gotta go, but they aren't talking to each other about their plans and have somewhat different priorities.
97	** The oil companies on Homeline are funding Greenpeace, who oppose the exploitation of other worlds. Said oil companies are trying to make outtime operations harder to preserve their own dying markets.
98	* EqualOpportunityEvil: Centrum is explicitly called out as finding the concept of discrimination based on race and gender very strange. They're a little more lenient on social divisions, but that's because they're [[AsskickingLeadsToLeadership meritocrats]]. (They also have an unconscious bias towards the English language and culture.)
99	* EvilCannotComprehendGood: A side-effect of Centrum's ideological uniformity is that Centrans don't really get that anyone might not think like they do. To them, democracy is a historical aberration associated with Greek and Italian city-states, an AlienNonInterferenceClause with underdeveloped worlds is considered paranoia rather than an attempt to protect the weak, and they're kind of scared just how well Homeline manages to prosper when Infinity "can't control" all the various bickering powers - the idea that Infinity might not ''want'' to be a OneWorldOrder doesn't even cross their collective mind.
100	* EvilerThanThou: What may happen when Centrum and Raven Division finally meet. Centrum are EqualOpportunityEvil meritocrats, while Raven Division... [[StupidJetpackHitler are]] [[{{Ghostapo}} Nazis]].
101	* EvilIsDeathlyCold: Nergal's oncoming Ice Age appears to be a result of the gates of Hell opening. It's anyone's guess just how literally to take this.
102	* ExpendableAlternateUniverse: With honorable exceptions, neither Infinity nor Centrum quite view people from other worldlines as ''real''. Among other things, the book notes that some Homeline filmmakers have taken to filming real battles on other worldlines with thousands of people dying to use as footage in their historical epics, and tourism to some distasteful place like Dixie-1's CSA (where slavery and racial segregation are still quite legal) is thriving.
103	* FantasticRankSystem: Centrum dispenses with individually named ranks almost entirely[[note]]Unattached are a special case of Grade 7[[/note]], using a numbered scale that starts at Grade 1 (the default for every citizen) and ends at Grade 7 (top-level coordinators of each Service that set policy for Centran society and have some authority even across Service lines).
104	* ForScience: Apart from the Gernsback parallel, which plays this straight (if mostly benevolently), there's an interesting variation with the Cabal (For Magic!).
105	* FromBadToWorse:
106	** Many in the know on Homeline consider Reich-5's discovery of parallel worlds to be this; while their own version of parachronic travel is, so far, ''much'' less effective than that of Homeline and Centrum, it could potentially end up forcing Homeline in a two-front conflict, as the latter's dimensional coordinates are between the other two.
107	** A potentially even worse case showed up recently on the former myth parallel once designated Oppenheim: Once an Edwardian/WWI-era world with some myth parallel elements, the [[UsefulNotes/TheSpanishFlu Spanish Flu]] hybridized with the Gotha virus to create the Gotha-Z strain -- which creates ''actual'' [[ZombieApocalypse undead]].
108	* {{Ghostapo}}:
109	** Reich-5's Raven Division uses quite a bit of Aryan magic to facilitate their world-hopping.
110	** The Condor Group from Merlin are Nazi mages who fled to Argentina after UsefulNotes/WorldWarII and formed an alliance with the Peróns. They've recently formed a low-level alliance with Reich-5's Armanen Order.
111	** The Ahnenerbe ''did'' come up with a lot of arcane lore in Taft-1, but never really managed to put it to use. [[spoiler:Captured Nazi occultists then helped fuel Stalin's development of Azathothic power.]]
112	* GreyAndGrayMorality: The conflict between Centrum and Homeline, where neither can be easily categorised as pure good or completely bad.
113	* HellOnEarth: Nergal is implied to be in the beginning stages of this. All of its surviving gods demand HumanSacrifice, and the world is descending into an [[EvilIsDeathlyCold anomalous ice age]] couched in melodramatic terms.
114	* KilledToUpholdTheMasquerade: Stringently averted by the Time Patrol; Centrum has less scruples, but there are few situations where they'll bother (see just below).
115	* InterserviceRivalry: While the Infinity Patrol largely averts this internally (in part because Patrolmen are ''expected'' to transfer between divisions as part of their job), Patrolmen don't always get along with the "corporate" side of Infinity, and both groups consistently join together to oppose any interference from the United Nations agencies that theoretically oversee Infinity.
116	* JokeLevel: The United States of Lizardia parallel. A world almost socially identical to Earth, with neo-troodons who use biotech and fluid-dynamic science in place of Earth technology, and the book explicitly points out that nobody is even trying to make any sense out of it. As far as anyone studying it is concerned, it's a practical joke by the gods.
117	* LiteraryAllusionTitle: The chapters dealing with example alternate timelines and time travel are respectively [[Creator/AndrewMarvell "Worlds Enough..." "And Time"]].
118	* LizardFolk: The chief inhabitants of the United States of Lizardia evolved from [[UsefulNotes/StockDinosaursTrueDinosaurs troodons]] -- though, rather bizarrely, [[InSpiteOfANail their recent history still closely parallels Homeline's]].
119	* LowCultureHighTech: Homeline, oddly enough, is slipping into this. The majority of Homeline's cutting-edge technology is "parachronic spinoffs", which is a euphemism for [[ImportedAlienPhlebotinum stolen outtime technology]], and as a result, Homeline's own scientific development is starting to stagnate while such things as fusion power are adapted wholesale without a firm understanding of the theory.
120	* TheMagicComesBack: The Merlin worlds, parallels where Hellstorms locally warped the fabric of reality and brought magic back to modern-day Earth.[[note]]Two of these parallels are the settings for ''TabletopGame/GURPSTechnomancer'' and ''GURPS: WWII: [[{{Ghostapo}} Weird War II]]''.[[/note]]
121	* {{Magitek}}: Exists on worlds where magic and technology have both been developed.
122	** Merlin has the most advanced version yet seen, to the point where magic has been seamlessly integrated into the world's technological infrastructure.
123	** Azoth-7 has a weird version, where alchemical developments have led to something that looks rather like Victorian science fiction, only a hundred years earlier and with a completely different form of technology.
124	** Homeline's Paralabs have been trying to develop some, but it's mostly seen as a curiosity rather than a serious pursuit, as Infinity is mainly a technological organization. For example, they came up with a really weird conveyor that ran on ClapYourHandsIfYouBelieve... and it and its inventor vanished in the first test.
125	* TheMasquerade: Infinity policy is to not reveal "the Secret" of parachronics to any outsiders, and to actively sabotage anyone else's attempts to do so; people who learn the Secret may be kidnapped and sent to [[PenalColony Coventry]]. Centrum is less anal-retentive about it; they only care if the natives learn about them on planets advanced enough to develop parachronics. However, when that happens, they tend not to let technicalities (like the right to live) get in the way of business.
126	* MegaCorp:
127	** Infinity Unlimited is structured as a corporation, though in practice it functions more as a U.N. agency.
128	** White Star Trading was Paul Van Zandt's original crosstime trading firm and the main source of seed capital for Infinity.
129	** Consolidated Mines, Unlimited was formed by a [[RichardNixonTheUsedCarSalesman parallel-world Cecil Rhodes]], who combines low-tech and high-tech mining techniques to bring home more raw materials than anyone else. Rhodes himself made a move to get elected to the Infinity board of directors, and took advantage of the [[NoJustNoReaction expected outcry from Africa]] to [[ManipulativeBastard split his operation off from Infinity]].
130	** The Yugorovsky Group are a [[TheMafiya Mafiya]]-affiliated mining conglomerate known for being [[CorruptCorporateExecutive ruthless, deadly]] and [[GovernmentConspiracy tied into the Russian government at the highest levels]]. They often engage in proxy wars with CMU.
131	** Johnson Crosstime Inc. has invested itself so heavily in Rome-2 that they effectively run the place, having turned the Roman Empire of that world into a massive tourist trap.
132	* MentalTimeTravel: World Jumpers.
133	* MildlyMilitary: Nobody really tries to regulate ISWAT teams. This is largely because said teams tend to be composed of the elite of the elite, with powers that don't really fit into operational doctrine, and also because over half don't even come from Homeline. They specialize in cosmic-level threats that involve the fate of multiple Earths, so they get a fair amount of slack, and Infinity pretty much expects that ISWAT teams on R&R will leave whatever town they're dropped in in ruins.
134	* MoralityKitchenSink: All possible ShadesOfConflict can be found in the Infinite Worlds. To save time: Infinity and Merlin-1's CIA are largely good guys, but both Homeline and Merlin have some serious rot in places. The Cabal are a WildCard and generally unpleasant people, while the Centrum are [[WellIntentionedExtremist Well-Intentioned Extremists]]. And then there's ThoseWackyNazis, and ''then'' there's people who make the Nazis look positively benign.
135	* TheMultiverse: Of or for GURPS.
136	* MultiversalConqueror:
137	** Both Centrum and Reich-5's Raven Division count, for different motives: Centrum [[WellIntentionedExtremist thinks they're civilizing alien realities]], Raven Division because they're [[ThoseWackyNazis greedy Nazis]].
138	** On Homeline, Infinity generally tries not to act like this... but there is no AlienNonInterferenceClause, and they're not against [[GovernmentConspiracy behind-the-scenes guidance]] of non-Homeline humans, or stealing technology and art from other parallels for Homeline's benefit. They also have to ride herd on sharp entrepreneurs who have their own ambitions:
139	*** Johnson Crosstime, Inc. ended up taking over Rome-2 because Infinity didn't read the fine print on his business license. By the time they realized what he was doing, the situation had become insane enough that they threw up their hands and ratified his buyout of the Roman Empire (luckily for the locals, he's a fairly BenevolentBoss and a human rights advocate; slavery is already beginning to be phased out thanks to him).
140	*** The Yugorovsky Group and TheMafiya send a lot of their members out to primitive worlds to "play czar," taking over nations to exploit them for their Homeline masters.
141	*** Infinity themselves have drawn up plans for the [[GodzillaThreshold annihilation of the governments of Reich-5]], in concert with Homeline's militaries. Operation Firefall was shelved because it was too risky and promised an appalling number of casualties even if Homeline won.
142	*** For some reason it seemed like a good idea to Infinity to put an alternate Cecil Rhodes in charge of mining operations on multiple Africas. There's no evidence he's become one of these ''yet'', but some people in Infinity think it's just a matter of time.
143	*** Infinity has an operation going on in the South Africa of Nergal, where they pose as gods and wizards who rule over the local Zulus and occasionally lead them in SlaveLiberation raids against the other nations of Nergal. This is presented as [[TheExtremistWasRight a good thing]], as the other major nations of Nergal all practice HumanSacrifice and are possibly leading the world to ruin through their BlackMagic.
144	* NGOSuperpower: Infinity Inc. is probably the most powerful entity on Homeline economically and politically. Only a partial example, as Infinity is technically a U.N. member organization. (In practice, Infinity doesn't answer to anyone.)
145	* NiceJobBreakingItHero: The snafu that resulted in the Reich-5 SS discovering parallel worlds and how to reach them was originally a Russian attempt to aid the partisans of the Reichsostland.
146	* NonindicativeName:
147	** The "Gotha" parallels, and the plague named after them. The name came about because the first such world that Infinity discovered looked like it was just a particularly bleak Dark Ages parallel where Visigothic berserkers had destroyed every city in their path. It was only later that Infinity discovered that things were [[ZombieApocalypse far darker than that]].
148	** A poetic-to-the-point-of-nonindicative name is the "Lucifer" series of worlds. No, these are not worlds defined by the presence of [[{{Satan}} Big Red]], they're worlds that have become or are becoming uninhabitable through [[ColonyDrop a meteor strike]].
149	** "Siva" is a generic term for India-dominant parallels. Humorously, the first Siva world discovered was actually dominated by ''Jainism'', not Hinduism.
150	** In Infinity, the "Morale Division" of the I-Cops is a euphemism. Their actual job is [=PsyOps=], which includes PR and political manipulations not just outtime, but on Homeline. It's safe to say that they don't want to be too obvious about the latter.
151	* NoSuchAgency: ISWAT doesn't exist. There's no special unit within the Patrol made up mostly of outtimers who handle missions that can affect the destiny of entire parallels. There aren't any training missions that involve StuffBlowingUp in infinite Nazi Germanies. And most especially, no [[RichardNixonTheUsedCarSalesman parallel Otto Skorzeny]] was ever enlisted to head up this nonexistent unit. That would just be silly.
152	* ObviousCrossoverMethod: As mentioned under the Canon Welding entry, the setting itself was basically built to allow crossovers to happen by way of interdimensional travel.
153	* OtherMeAnnoysMe:
154	** The head of ISWAT, [[RichardNixonTheUsedCarSalesman Otto Skorzeny, comes from a world where he was a heroic freedom fighter against Hapsburg tyranny]]. He's a firm believer in freedom and human rights, and ThoseWackyNazis are the antithesis of everything he stands for, which means that he wants to shoot every one of his alternate selves who took up the swastika.
155	** One of the vignettes has a bunch of alternate [[Creator/LordByron George Gordons]] meet up together. They've all had different life experiences, but one thing they have in common is an exceptionally strong personality. They promptly start arguing with each other until [[spoiler: the vampire Byron shows up, and is then disposed of by Lady Georgia Byron]].
156	* OurGeniesAreDifferent: On Caliph, a scientifically advanced Arab-dominant timeline, references to djinn in the Qu'ran are [[TheGenieInTheMachine believed to be prophecies of A.I., and actual A.I. are called "djinn"]].
157	* OurVampiresAreDifferent: It's implied that most traditional versions of vampirism show up somewhere in the multiverse.
158	* PatrioticFervor: This is a major pain in the ass for Infinity. Every major power on Homeline wants to support its parallel selves, even if they're kind of nasty (Infinity isn't allowed to mess with Bonaparte-4's France because Homeline's France is blocking it) or if their actions endanger the Secret (such as Russian involvement in the Reichsostland). This does ''not'' apply to the Reich or Imperial Japan; Homeline Germany actually has plans to invade the former on Reich-5 (although tabled indefinitely due to the projected prohibitive cost in lives), and Japan has no fondness for the latter except in [[ZombieApocalypse exceptional circumstances]].
159	* RagtagBunchOfMisfits: ISWAT teams have a tendency to be the BadassCrew version of this. Over half of ISWAT members are outtimers recruited for a variety of reasons, and include such things as wizards, psychics, vampires and weirder things, mixed with a solid core of tough and lucky Patrolmen. Said teams engage in live-fire sabotage against Nazis as training missions.
160	* RaygunGothic: Several timelines are defined by a mid-20th-century SF aesthetic; notable examples include those described in ''[[https://www.sjgames.com/gurps/books/worldsofatomichorror/ Worlds of Atomic Horror]]'', as well as Gernsback.
161	* RedScare: Merlin-1's America ''hates'' Commies, and their reaction to discovering the dominance of the Soviet Union in Taft-1 was to send in Black Berets to redo the Vietnam War. This is potentially a '''''VERY BAD THING''''':
162	-->"However, they’ve encountered something even worse than Red aggression: a scattered tribe of dwarfish cannibals (the Chaucha, or [[Franchise/CthulhuMythos Tcho-Tcho]]) that uses magic -- [[WrongContextMagic but not any kind of magic Merlin-1 understands.]]
163	-->"On Taft-1, it’s 1962, and Stalin still lives. [[EldritchAbomination And he has worse allies than Hitler.]]"
164	* ReedRichardsIsUseless: Averted. Parachronics are making Homeline a better place in many ways -- one of the most obvious is the fact that with a seemingly unlimited number of uninhabited parallels to exploit, resource conflicts have become a thing of the past. Nevertheless, Homeline's seedier elements are finding ways to use the infinite worlds to support ''their'' agendas as well.
165	* RepressiveButEfficient:
166	** Centrum is actually a decent place to live, so long as you don't mind being under constant surveillance and having no individual rights. Everyone gets their needs met and proven agents live comfortable 21st-century lifestyles, in part ''because'' they have combined socialist economics with infinite resources. Their Interworld and Uplift Services have the backing of an entire world behind them and have established several colony and vassal worlds, and their agents are terribly capable adversaries for Infinity. The weakness of their repressiveness is that it extends to their people's minds; Centrans generally [[EvilCannotComprehendGood don't get viewpoints that aren't theirs]] and can be tripped up by people not acting like they think they will.
167	** One vignette from the Centran side indicates that they think of the Nazis as this. The Centrans think that they're more "orderly" than Infinity because they're organized as a hierarchical dictatorship. The Centrans don't realize that the Nazi bureaucracy is actually utter chaos, riven with so much backstabbing that it's almost impossible to get anything done.
168	* RichardNixonTheUsedCarSalesman: It's par for the course for most timelines to have a bunch (apart from the odd instances that don't have ''any'', which is a research topic in itself). It's even possible to meet your own alternate-universe self, who likely as not will have a very different life experiences. In what may just be the Most Triumphant Example, the director of the Infinity Patrol's secret ISWAT special task force is... an alternate [[http://en.wikipedia.org/wiki/Otto_Skorzeny Otto Skorzeny]]. However, this Skorzeny was, in his home parallel, a freedom fighter for the [[RagTagBunchOfMisfits multi-national and -denominational]], proto-democratic [[TheRepublic Republican]] [[TheAlliance Alliance]] (in this timeline, European monarchies endured almost unopposed until the collapse of the Austro-Hungarian Empire in the 1930s), and really, really ''hates'' ThoseWackyNazis [[OtherMeAnnoysMe (especially when they're other hims)]], and so uses live-fire sabotage missions against them [[TrainingFromHell as part of the standard ISWAT training]].
169	* ScrewTheRulesIHaveConnections: The government of Israel is not a signatory to the Interworld Treaty, and is known for using it for toilet paper; in particular, it is standing Israeli policy to rescue Jews in trouble on all worlds and offer them sanctuary in Israel and the West Bank in violation of Infinity rules. The US' veto in the Security Council and UNIC prevents anyone from coming down on Israel for the Alternity Exodus.
170	* SlidingScaleOfAlternateHistoryPlausibility: Varies from relatively plausible timelines with minor changes from OTL (e.g. [[https://en.wikipedia.org/wiki/The_Day_the_Music_Died The Day the Music Died]] never happens and several music greats are less self-destructive, so they all continue to make music well past when they would have otherwise), to relatively unlikely histories (e.g. a Nazi [=WW2=] victory resulting from an isolationist USA) to very implausible (e.g. early invention of printing press leads to Muslim interplanetary colonization by the 1600s) to extreme AlienSpaceBats (e.g. Newton invents alchemy, summons an angel to destroy the Spanish armada, and Europe fights space battles over the celestial spheres). And then there's the United States of Lizardia, which is just [[JokeLevel plain silly]].
171	* [[SpaceColdWar Spacetime Cold War]]: Infinity vs. Centrum, although the presence of Reich-5 may or may not end up provoking a cross-temporal equivalent of World War II.
172	* SterilityPlague: Taft radiation, found on Taft-3, Taft-4 and Taft-7, causes sterility in primates. It's only doing anything on Taft-3, though; Taft-4 has other things going on and is partly shielded from the radiation, and Taft-7 never had any hominid life to begin with, the divergence dating to at least 16 million years ago. Someone upstairs at Infinity has ordered that Taft-1 be checked for Taft radiation as well. [[spoiler: Actually, the implication from Taft-1 is that it's weirder than that; the source of the radiation is implied to be ''[[Franchise/CthulhuMythos Azathoth]]''.]]
173	* StupidJetpackHitler: Reich-5, a world where the Nazis have taken over and developed some [[AppliedPhlebotinum superscience]]. They don't have world-hopping technology yet, but ''do'' have some innately gifted people who can do it.
174	* SummonBiggerFish: [[spoiler: On Taft-1, Case DEXTER is a Centrum plan (possibly from a secret splinter faction) to expose Infinity to Joseph Stalin, who in this parallel is an Azathoth cultist. Centrum doesn't actually like Soviet Communism at the best of times, Taft-1's Soviet Union is probably the most horrifically-evil USSR in the Infinite Worlds, and the Franchise/CthulhuMythos is completely antithetical to everything Centrum stands for, but Stalin is a potentially apocalyptic threat to Homeline if he discovers it.]]
175	* TechnicallyLivingZombie: Gotha zombies are actually alive; their brains have just been rotted into homicidal death cultists by the virus and their bodies turned into plague vectors. The Z-strain partially averts this, though; that one brings up actual undead when the infected die.
176	* TheRightOfASuperiorSpecies: Applied on the hell-world of Ariane, where human civilization was wiped out by a much deadlier [[UsefulNotes/TheSpanishFlu Spanish Flu]]. Infinity largely shrugs at the idea of enslaving stone-age survivors, but since Tibet has maintained a functional civilization under the lamas, Infinity has told the colonists to leave them alone and not try any freebooting there.
177	* TheThemeParkVersion: Deliberately invoked by Johnson's Rome, where Johnson Crosstime Inc. has all but bought out the local Roman Empire, and then gleefully pumped up the "fun parts" of the already pervasive decadence it was riddled by (fortunately for the locals, Johnson is both practical and modern in his outlook, so he's also arranged for a gradual phasing-out of the more unsavory aspects).
178	* ThoseWackyNazis: There are six known parallels with Nazi Germany victorious to some degree, most notably Reich-5, where a subfaction of the Nazi apparatus have discovered parachronic travel and joined the war across the Worlds. Taft-2 downplays this, in that Nazi Germany survived until 1949, at which point [[InSpiteOfANail the Wehrmacht knocked Himmler off]].
179	* TimePolice, alternate-history style.
180	* TimeTravel: But to [[AlternateHistory alternate timelines]] instead of the actual past or future (unless the GM decides to mix it up), partly to avoid TimeyWimeyBall-related problems like those nasty {{temporal paradox}}es.
181	* TotalitarianUtilitarian: Centrum values human life and prosperity very highly. That is, they value the lives of ''all'' Centrans, and to a lesser extent outtimers, very highly. If individual rights and lives have to be sacrificed for the greater good, that's simple practicality, and a rational person would be honored to make that sacrifice.
182	* TrainingFromHell: The Academy; one year spent in the middle of an Ice Age. The big weeding drill in the middle is being dumped in the middle of the frozen wilderness [[WithThisHerring in your sleepwear, with whatever you can grab five minutes after the alert]] and told to find your way back home. If you succeed, you get a week off in a freewheeling primitive world to do what you like... and if you can't keep it together and adapt to the local environment while on "leave", that's another easy washout.
183	* TheTunguskaEvent: [[spoiler: In Taft-1, the Tunguska bolide's remains contained the... whatever it was that allowed Stalin to "sign his name in the book of Azathoth" in 1927, thereby becoming an immortal Franchise/CthulhuMythos cultist-sorcerer, and beginning the Soviet Union's Mythos-fueled ascendancy.]]
184	* UsefulNotes/UnitedNations: Though the UN itself is being usurped by Infinity, which essentially doesn't answer to anyone.
185	* TheUsualAdversaries:
186	** Homeline's Infinity and Centrum's Interworld Service serve as this for each other, as their respective worlds are the only ones that have full access to parachronic tech. They are directly competing against one another to spread their influence and secure any potential "back doors" into their homeworlds.
187	** Reich-5 has started to compete for the spot in Infinity's eyes, as Nazi evil begins to spread across the Infinite Worlds. They're newcomers compared to Centrum, though. (They're too far away from Centrum for the latter to care much, and Centrum doesn't know the Nazis as anything more than a bunch of outworld madmen.)
188	* WeAREStrugglingTogether:
189	** Possibly Infinity's greatest handicap in its parachronic operations (especially compared to the mostly unified front Centrum presents) is that a LOT of Homeline's various governments, corporations, [=NGOs=], and even criminal groups have access to parachronic tech (legally or otherwise) and use it to push their often wildly conflicting agendas across the parallel worlds. Consequently, a lot of their resources are tied up monitoring, policing and otherwise cat-herding all these groups.
190	** The Cabal is another example, as it's basically made of several different groups of supernaturals and magic-users with often widely divergent goals and philosophies. To its more technologically-inclined rivals Infinity and Centrum, this doesn't make it any less threatening, though, as this (among other things) makes it the biggest WildCard of the setting.
191	* WeirdnessMagnet:
192	** Worlds in which senator [[http://en.wikipedia.org/wiki/Robert_A._Taft Robert A. Taft]] is/was president have either magic, an artificial spacecraft of unknown origin in orbit around Saturn or, most frequently, a peculiar sterilizing radiation [[spoiler:whose source is heavily implied to be ''[[Franchise/CthulhuMythos Azathoth]]'']]. Taft-6 seems to only be a "normal" world with slightly higher-than-usual mana and no radiation, and the Infinity Patrol are going nuts trying to figure out what's actually happening.
193	** Something about Cyrano attracts sheer insanity to the world; problems there tend to involve wizards, gods and lunatics (in no particular order), and France Outremonde has been corrupted by something otherworldly that doesn't look like a Centrum plot. Regular Patrol units are out of their depth here; missions on Cyrano call for ISWAT, and the fact that Centrum is regularly operating there suggests that they might be setting up an ISWAT of their own.
194	** Even the most routine trips and missions to Tsarevich tend to be so fraught with unpredictable problems and complications (up to and including outtimers and Patrolmen involuntarily becoming GothicHorror monsters and villains) that the phenomenon is known as the "Tsarevich Curse" by Infinity personel. It's not helped by the worldline's main hotspot being [[{{Uberwald}} the region in and around the Balkans]]. [[spoiler: Unbeknownst to Homeline, this is due to interaction between parachronic radiation and the fragments of a prehistoric meteorite reality shard.]]
195	* WellIntentionedExtremist: Centrum's default moral status. They're ruthless, hegemonic cultural imperialists, but they're trying to save each parallel they're operating in from undergoing their own versions of the [[TheEndOfTheWorldAsWeKnowIt Last War]].
196	* TheWorldAsMyth: There are more than a few parallels based on explicitly fictional settings, called "myth parallels." Their existence, as well as the possible implications they have for how parallel timelines come into being, baffle and annoy serious parachronics researchers.
197	* WrongContextMagic:
198	** [[spoiler: Azathothic "magic" is actually [[ClarkesThirdLaw sufficiently advanced technology]] that requires no infrastructure and is based in pure mathematics. Unlike most magic, it works on ''any'' worldline, period, and can't be blocked by anti-magic effects. It's vaguely linked to PsychicPowers, but only to an extent, and anti-psi effects only negate the bonus gained through psychic talents - they don't nullify the ritual itself. Also, working with it naturally corrupts the mind and soul, but what did you expect when dealing with the Mythos?]]
199	** Infinity Unlimited is used to using parachronic conveyors as their favored world-crossing method, and world-jumpers are their next best-understood methodology. Infinity also has an entire ''division'' of I-Cops (Nexus Oversight) dedicated to dealing with other methods of crossing realities, since none of these are based in the standard quantum pattern and many can be used to allow crossings where they "shouldn't"; in particular, they want to secure any possible backdoors into Homeline.
200	* ZeppelinsFromAnotherWorld: The random timeline generation has a specific result that produces these, by the book's own admission (see the quote on that page) driven by RuleOfCool; several canon parallels also have them, of course.
201	* ZombieApocalypse: The Gotha parallels. Gotha zombies are [[TechnicallyLivingZombie carriers of a prion-based disease]] that mutated from the pneumonic plague, which retain some of their previous intelligence and memory, as well as just enough wherewithal to hold onto old cultural beliefs (usually with a strong slant towards fatalism and death worship). Thus why the zombies discovered on Gotha-1 were described as Visigothic berserkers; another Gotha parallel had zombie Thuggee in India. On Gotha-Z, the Gotha factor somehow "jumped" onto the Spanish Flu during the pandemic's apex; not only did that version prove just as effective as the standard one at turning its carriers into frothing homicidal psychos, but when killed, those infected lose the "technically living" and rise again as actually undead zombies.
