A cycle of six {{Doorstopper}} books by Creator/HarryTurtledove which covers the story of UsefulNotes/WorldWarII from a global perspective, using [[LoadsAndLoadsOfCharacters Loads And Loads Of Viewpoint Characters]] from all the major participant nations ([[AndZoidberg and Finland]]). The twist is that this is not the UsefulNotes/WorldWarII ''we'' know, but the same sequence of events transposed onto a generic LowFantasy world which has used FunctionalMagic to achieve industrialisation. Fantastic equivalents for real weapons and technologies abound: dragons for aircraft, leviathans for submarines, behemoths for tanks...

One of the more interesting twists is that the [[FantasyCounterpartCulture Fantasy Counterpart Cultures]] do not match up with the countries they're representing: Turtledove randomly mixed ethnicities and used languages and place names from more obscure countries. For example, the nation of Kuusamo is the equivalent of the United States, but is inhabited by Finnish-speaking East Asians. This allows the reader to take a slightly more objective view of the conflict.

In addition to this, most of the continents are in the southern hemisphere of this planet, east and west are flipped but north and south are not. This means countries which are cold in RealLife are often hot in the Darkness world and vice versa: for example, Zuwayza (Fantastic Finland) is a red hot desert country while the Land of the Ice People (Fantastic North Africa) is an icebound wasteland.

!!This book series contains examples of:
* AlternateHistory: Sort of, appropriately enough given Turtledove's other works. Putting things in RealLife terms, this version of UsefulNotes/WorldWarII starts when Germany marches into Danzig--Poland is not conquered until the end of the first book. Britain isn't a member of the Allies from the start. And America and Japan are already at war before the main war begins.
* AmericaSavesTheDay: Largely averted; Kuusamo plays the same major role as the United States in RealLife, but it's made clear that it's the Unkerlanters (Fantastic Soviets) who do most of the fighting.
* AnyoneCanDie: Plenty of viewpoint characters die after featuring in multiple books. They are often replaced by one of their friends or comrades who we've already met in their narrative to ease the transition. (Turtledove also uses this trick in some of his other series).
* BoomStick: The weapons known only as "sticks" that infantry use in lieu of guns, being a sort of mass-produced magic wand or wizard's staff that fires an energy blast when a finger is placed into the firing hole. The blasts can be attenuated by heavy rain.
* BroadStrokes: This is a fantastic version of UsefulNotes/WorldWarII, but not everything exactly matches up, the order of events is sometimes different, and expectations are played with.
* BrotherSisterIncest: Not an actual example, but invoked: Kaunian Vanai creates a spell which allows her to take on a Forthwegian appearance, in order to hide from the Algarvians. Her Forthwegian lover Ealstan is a bit {{Squick}}ed that the spell for some reason makes her look almost exactly like his sister Conberge.
* TheCaligula: King Swemmel (Fantastic UsefulNotes/JosefStalin), who boils his enemies in huge kettles. Oddly enough, King Mezentio (Fantastic UsefulNotes/AdolfHitler) comes across as less crazy (but strong-willed), although he's rarely seen.
* CrazyCulturalComparison: Turtledove likes this trope; there are constant cultural comparisons between the various racial groups and countries -- some fairly unpleasant. The one that sticks out is the fact that the people of baking hot Zuwayza commonly go naked except for a wide-brimmed hat and sandals. Most foreigners consider this bizarre, but the ambassador from Algarve goes native - though he still gets funny glances from the Zuwayzi as Algarvians are all circumcised.
* DragonRider: Deconstructed -- while dragons are commonly used for aerial combat, they are nasty, foul-tempered, violent, and stupid creatures who have to be cruelly treated from birth in order to discourage them from killing their riders.
* FantasticNuke: Pekka's storyline is about the magical equivalent of the Manhattan Project. The FantasticNuke is finally used at the end of the last book, [[spoiler:but in a slight change to real history, only one is used and it's used against the capital of the Japan equivalent, killing their emperor equivalent]].
* FantasyConflictCounterpart: The series is about a fantasy version of WWII. With MagicMissile shooting "sticks" as guns, dragons as aircraft, behemoths for tanks, leviathans for submarines, earthquake-generating spells powered by HumanSacrifice in place of airstrikes, the America equivalent even develops a FantasticNuke.
* FantasyCounterpartAppliance: Sticks for guns, crystals for radios (these effectively being standardised, mass-produced magic wands and crystal balls respectively), egg-tossers for artillery.
* FantasyCounterpartCulture: The ''Darkness'' series does this rather directly, but subverts it somewhat by mixing and matching cultures around -- for example, the equivalent of Nazi Germany has Celtic ethnicity and Italian language.
** Also done for the purpose of irony as the fantastic equivalent of Jews are described as being fair and blond (the Nazis' espoused "Aryan ideal") and implied to be the remnants of the equivalent of the Roman Empire (which Nazi Germany took many motifs from). Furthermore, the Algarvians are circumcised.
* ForegoneConclusion: Once you've figured out who's who, you know who's going to lose--although not everything is ''exactly'' like our UsefulNotes/WorldWarII.
* FunctionalMagic: Rule Magic (spells are weakened by proximity to water, while they are powered up when close to "{{ley line}}s") and Device Magic ("sticks" and "eggs", magical equivalents of guns and bombs, respectively), as well as some forms of Alchemy. The Nazi-analogue Algarvians also make use of a kind of Black Magic toward the end of the war, as a last resort; it's powered by mass human sacrifice, drawing upon the many ethnic prisoners they took over the course of the conflict. There's also a magical Manhattan Project, utilising heavily mathematical and rigorous investigation of the fundamental laws of magic, much akin to the study of physics.
* HumanResources / PoweredByAForsakenChild: The Algarvians' Holocaust-powered superweapon, which uses mass human sacrifice in what is implied to be a DealWithTheDevil, or rather the Powers Below.
* TheLawsOfMagic: At least two of them, including the [[LocardsTheory Law Of Contagion]].
* MagicAIsMagicA: Like all Turtledove's fantasy settings, this one runs on two basic rules of magic--the "Law of Similarity" (two visually similar things are magically connected) and the "Law of Contagion" (two things that have touched are magically connected). Research magicians find a new universal principle connecting the two laws, which allows them to make a FantasticNuke.
* NoHistoricalFiguresWereHarmed: Mezentio is Hitler, Swemmel is Stalin, etc.
* OhMyGods: Most countries' people seem to follow roughly the same dualistic religion, and swear by "Powers above!" and "Powers below!" The Gyongyosians, being the odd one out, instead worship the stars, and swear by them. The Ice People are the only ones whose religion actually mentions 'gods' and they are considered backwards and primitive by everyone else.
* OurDragonsAreDifferent: They're considered rather stupid creatures that 'pilots' have to beat with crops to get them to cooperate.
* OurNudityIsDifferent: The Zuwayzi have no nudity taboo due to the heat of their homeland leading them to mostly go naked except for a wide-brimmed hat and sandals.
* PeopleOfHairColour: Used extensively; hair colour, along with clothing (kilts vs trousers vs tunics) is the main racial identifier. Algarvic (Fantastic Germanic) peoples like the Algarvians, Sibians and Lagoans (Fantastic Germans, Danes/Norwegians and British) have red hair. Kaunian (Romance and Jewish) peoples like the Jelgavans, Valmierans and the Kaunians of Forthweg (Low Countries, French and Jews of Poland) have blond hair. The 'Slavic' peoples of Unkerlant, Forthweg and Grelz (Russia, Poland and Ukraine) have brown hair.
* ThePlotReaper: When Pekka and Fernao, both major characters from the beginning, finally meet at the series' halfway point, they slowly start to fall in love with each other; Pekka is married, but both she and her husband Leino are being kept in total isolation with their colleagues working on separate top secret projects. Meanwhile, Leino's shagging one of his coworkers (who aside from her looks really has nothing going for her) with far fewer reservations. This could have created a very complicated and messy situation when everyone met, but instead Turtledove kills Leino and his lover at the beginning of the last book. Somewhat played with as news of Leino's death (but not his affair, no one ever finds out about that) initially makes Pekka feel enormously guilty and break off her relationship with Fernao, though eventually they get back together and get married.
* RockBeatsLaser: The Algarvians are able to conquer Sibiu in a surprise attack by using a fleet of 'primitive' sailships which aren't often used for military operations anymore; everyone assumes that an invasion fleet would be made up of magical leyline-using floating ships, which can be magically tracked.
* WearingAFlagOnYourHead: Dragons and other war creatures are painted in the colours of the countries' flags or military uniforms: for example, Algarve uses red, white and green, Kuusamo uses sky-blue and sea-green, and Unkerlant uses rock-grey.
* YourNormalIsOurTaboo: The Gyongyosians (Fantastic Japanese) have a taboo about eating goat meat. The Zuwayzans (Fantastic Finns) wear little to no clothing due to the heat of their country. Individual members of the Ice People (Fantastic North Africans) have particular fetish animals whose meat they will not eat. Algarvians are all circumcised at the age of fourteen, which the other nations find to be a strange practice.
