Spelljammer is an Advanced Dungeons & Dragons setting that adds up to D&D in SPACE. It has a small but loyal following. Created during a dark era of Executive Meddling (see Trivia.Spelljammer for details), it was an attempt to cash in on the popularity of the Standard Sci Fi Setting in a fantasy RPG.The premise of the setting is to link each of D&D's then-popular campaign settings together by means of the old Ptolemaic view of the cosmos; the worlds of Greyhawk, Dragonlance, and the Forgotten Realms were (along with thousands of other worlds) stated to be contained in their own "crystal spheres", massive hollow balls large enough to contain a whole solar system. Some were heliocentric systems, sometimes geocentric, and some were flat worlds set upon the backs of great tortoises or other starbeasts. Or something else entirely. The stars you see from your bedroom window are not other suns — they're actually balls of light (or glowing gems) stuck to the interior of your world's crystal sphere. Unless, of course, you're in a sphere that got giant glowing beetles slowly crawling on its inside surface. It happens.Flying ships, called spelljammers (not to be confused with the Spelljammer, a legendary ship miles in length) traverse wildspace, the void within each sphere, traveling from world to world (which always seem to support life no matter their distance from the sun). The ship picks up an "air envelope" when it leaves the atmosphere, so breathing is limited by the number of crew and the size of the ship, and gravity is always directed toward the deck from both above and below. And outside the crystal spheres (accessible through natural portals or transportation magic), lies the Phlogiston (or "the Flow"), a gaseous, highly incendiary substance that's all the colors of the rainbow and lets your ship travel at warp speed as long as you're in one of its currents.Spelljammer was utterly preposterous, didn't really care one whit about real-world astronomy or physics, and was completely aware of this. Never taking itself all that seriously, it was one of the few inherently fun games that TSR was permitted to publish in that era. A very brief list of some of the things that you will find in Spelljammer, besides a deliciously crazy mish-mash of everything D&D has to offer: Weird Science, Space Pirates, Giant Space Hamsters, Stuffy BritishElves (who are of course Better), and Gnomes who think that catapults are a good replacement for staircases.Due to the limited print run (again due to Executive Meddling), the Spelljammer materials can mainly be found at DriveThruRPG.com.A parody setting released by the guys who made Hack Master, HackJammer, attempted to fit the setting to a well-tested set of rules that made it more playable, but for many it was too little too late.A 3rd edition remake of the setting appeared in an issue of Dungeon Magazine. While thematically identical to the original Spelljammer (although with its own default campaign setting limited to a single system), it removes the Phlogiston/Crystal Spheres to replace them with the vacuum of space and star systems/galaxies, with the notable difference that suns are also portals to the Elemental Plane of Fire with their own atmospheres and natural satellites (apparently magic still outright replaces physics). Additionally, a later issue of Dragon Magazine included 3rd edition versions of popular Spelljammer races. Other than that it was mostly abandoned (no proper products) and left to fans.Spelljammer received some references in Fourth Edition material: It was one of the settings listed as possible to see print, and some Spelljammer content has made it into the Manual of the Planes (as a ship to sail the Astral Sea and to use to Plane Shift) and Forgotten Realms Campaign Guide (specifically referring to the crystal spheres and phlogiston). Sadly, nothing came of this; as 4e ends there is no Spelljammer in sight (though an Epic Destiny in Heroes of The Elemental Chaos lets you become a Regiar). Mike Mearls said that this wasn't so much due to Spelljammer being too silly but rather how hard to pull off the crossover aspect is. He said that if they were going to do it in D&D Next it'd be "its own thing"There's one series of novels (The Cloakmaster Cycle), one short-lived DC comic book series, and one Video Game (Spelljammer: Pirates of Realmspace) using this setting. The dedicated fan portal also tracking usenet groups and keeping mirrors of Spelljammer fan-sites that go down is spelljammer.org.
Always Chaotic Evil: One of the first major D&D settings to start playing with this, from Nazi elves, to a community of relatively decent illithids, to a non-evil mutant Beholder bartender.
Artificial Gravity: Technically, gravity "carpets" on small objects were a natural phenomenon.
Attack of the 50-Foot Whatever: Including breeds like the Subterranean Giant Space Hamster, Sabre-toothed Giant Space Hamster, Rather Wild Giant Space Hamster, Invisible Giant Space Hamster, Sylvan (or Jungle) Giant Space Hamster, Miniature Giant Space Hamster (otherwise known as...a hamster; the breeding came full circle...), Armor Plated Giant Space Hamster, Yellow Musk Giant Space Hamster, Ethereal Giant Space Hamster, Carnivorous Flying Giant Space Hamster, Two-Headed Lernaean Bombardier Giant Space Hamster, Two-Faced Giant Space Lagan Hamster, Fire-breathing Phase Doppleganger Giant Space Hamster, Great Horned Giant Space Hamster, Abominable Giant Space Hamster, Tyrannohamsterus Rex, and the legendary Giant Space Hamster of Ill Omen.
The Battlestar: Tsunami (Human—Wa), Armada (Elven) and Mammoth (Ogre) are heavily armed carriers of small crafts.
Space Fighter: The main limitation on such tactics is the cost of power sources for every warboat, thus Wa churn out rudders of propulsion for Locusts, elven Flitters are built upon starfly wings and goblinoid Blades use relatively cheap Death Helms (a.k.a. lifejammers).
Bishie Sparkle: The Reigar have this as an inherent part of their physical appearance, to the degree where they have weaponized it.
Even peaceful plants, such as starfly tree — its seeds leave the atmosphere and go Space Sailing until they meet a good icy asteroid. Then a seed roots itself, turns its shell into boiler with steam jets and slowly thrusts the ice boulder it sits on to a warmer orbit where it thaws.
Boisterous Bruiser: The giffs as a race—big hippo-people with a fetish for firearms. Seriously.
I think the Giffs were a little bit of the Humans Are Bastards as well. They seem to be meant to be a critique on human behavior with one source book even saying of the Giff something along the lines of "this is what happens to an intelligent race which evolves alone."
Captain Ersatz: The bionoids are basically mass-produced Guyver units, right down to the chest cannon.
Colony Drop: Not typically, but still, it's a possibility.
Zelva Twogg, Secretary for Wildspace Affairs, New Waterdeep: If we could find some way to tow that old dwarven citadel into orbit around our world, we'd have a fantastic station from which we could open trade to the other worlds in this sphere. We'd probably do best to contact some adventurers to do the work for us.
Skrund the Bald, Undermarshall for Pan-Goblin Affairs, New Trollmoor: If we could find some way to tow that old dwarven citadel so that it was heading right for New Waterdeep, we'd be rid of those damned humans in an eyeblink. We'd probably do best to contact some pirates or monsters to do the work for us.
Crossover: Spelljammer crosses over with Dragonlance, the Forgotten Realms, Greyhawk, and it can crossover with Planescape, but the two rarely if ever did because they were both ways for adventurers to visit different worlds. The setting has the potential to crossover with Ravenloft even, as it has been noted that the Mists can appear even in Wildspace, but the two have never really crossed over due to Spelljammer being a much goofier setting than Ravenloft.
Crossover Cosmology: Any imaginable cosmology is likely to be implemented in at least one crystal sphere. Somewhere.
Death from Above: Averted. A flying weapon platform obviously could have an enormous advantage over groundlings, but spelljammers are too clumsy in the atmosphere and thus are sitting ducks for anything that can get them. Spelljammer shock—which can be caused by any sort of damage—and failure to replace the helmsman in free fall before hitting the ground means Total Party Kill. Did we mention helms are expensive?..
An example: "The Three Greenwings Wars". IEF sent Monarch Mordent to aid the defenders of Myth Drannor. It helped a lot, but as the name implies, emerged in one piece from only two battles. The third time man-o-war descended to have a good shot, one nycaloth flies up and starts chopping a wing with great axe, simply ignoring most of the stuff elves can quickly hurl at him without breaking their own ship. The wing falls off, spelljammer shock kills their helmsman, the ship crashes.
Earth-Shattering Kaboom: The Master Stroke, which was the Reigar's grand attempt to achieve the ultimate artistic expression of war — by blowing up their own home planet! It's not an accident that most sane people try to avoid these guys.
Elemental Rock-Paper-Scissors: The distribution of Fire (suns) and Earth (planets) especially, determined the structure of a system, and the fact that Air tended to "stick" to objects and people made interplanetary and inter-sphere travel possible.
The Empire: The campaign-length adventure Under the Dark Fist introduced the Vodoni Empire, a totalitarian and expansionist human empire that controlled no less than twelve solar systems.
The Emperor: Vulkaran the Dark, overlord of the Vodoni Empire.
Expy: A lot of the races are recycled from the aliens in TSR's earlier sci-fi RPG, Star Frontiers. Rastipedes are based on Star Frontiers's vrusk, hadozee are yazirians, syllix are sathar, and plasmoids are dralasites.
There's human organization Xenos, guys who hate all other races.
Elven Imperial Navy are generally benign, but are haughty enough to annoy everyone else (Sindiath Line's readiness to receive less belligerent elves upkeeps this status quo). After which they are loudly aggrieved that it was Unhuman War. They have an especial hatred for goblinoids.
The branch on the Spelljammer is outright genocidal — planning to engage in a war of extermination against all goblinoids that is not portrayed favorably just because they're evil — but is fortunately prevented from actually acting on it by, well, being on the Spelljammer.
Normal gnomes tend to think that tinker gnomes make the whole race look like clowns; a few of them even go so far as to hunt down tinker gnomes' "ships" to wipe this dishonour off the space lanes. It's not that tinker gnomes weren't generally nice guys, but since minoimashupmachines are plain dangerous for any settlements they may try to land at, those who break them up before they fall on people's heads are at least as likely to be approved as condemned.
Beholders always run on this trope, but here they can engage in their pointless race wars in full view of everyone else with entire fleets going at it.
The Spelljammer includes, amongst its assorted races and factions, a tower populated by the Shou, an Oriental human culture from Kara-tur who regard everyone who isn't a Shou as a simple-minded, barbaric gaijin. They're led by a mad magistrate who believes he is the captain of the Spelljammer and has total control over life and death over everyone (he doesn't, not outside the Shou tower, anyway), while his aide, who really runs thing, is a secret member of the branch of the abovementioned Xenos and is planning on getting them to wipe out all non-humans so that the Shou can then conquer/eradicate the non-Shou humans.
Good Guy Bar: The World Serpent Inn mentioned in several sourcebooks was built in its own demiplane by an archmage from Toril, an Arcane and an Illithid as a neutral ground when Sigil turned out to be too violent and inconvenient for quiet business and rest. Not only is it connected to many worlds, but is accessible to powers, and some gods visit it to relax and chat with creatures they deem interesting. It's a Good Guy Bar since no one wants to annoy peacefully grazing deities, and some clients in a common room can turn out to be gods on a tea-break. And even if there aren't any, The Bartender is an avatar himself — if some god just likes to meet new people and thinks it's funny, why not?
Grey and Gray Morality: Scro vs. IEN frequently approaches this. Scro are Lawful Evil but honorable in their own way and elves are theoretically Good Guys, but they're official jerks who frequently poke into other people's business. Both think that a piratical attack on a neutral party is perfectly acceptable if there's a little chance to get the strategical advantage from it. In the Cloakmaster Cycle some IEN guys even topped it with a random murder just to show they're serious about it. While acting offended that others weren't too eager to join their side in the First Unhuman War, no less. Both try to control all the wildspace as they see fit; and as far as other races are concerned, neither the idea of bloodthirsty scro collecting tribute nor excitable haughty elves snooping around makes for a particularly ideal situation.
Hamster Wheel Power: Gnomish technology is often powered by giant space hamsters running in wheels.
Human Resources: The infamous Death Helms or Lifejammers operate by using the life force of a victim strapped into it to power the ship. They're a favorite of neogi and other evil spacefarers.
Humongous Mecha: Elven Spirit Warriors, giant undead artificially-grown insect bodies controlled by a pilot in the torso.
Living Ship: Although, technically, this was supposed to refer almost exclusively to the Spelljammer itself, it is applicable in a much less interesting fashion to the Elven vessels, which are shaped from a living spacefaring plant. Reigar Esthetics are more potentially dangerous as a lifeform, though just as mindless. Borderline cases are Tick — Neogi vehicle powered by life draining, designed to be used as a "saddle" for something big. And some people just live on the backs of kindori — they are big enough for a village and travel in herds.
Lotus-Eater Machine: The Spelljammer, in a sense. Part of its protective elements is that it fills the air envelope it produces with arcane pheromones that subtly enchant those who set foot aboard it and inhale its air. The charm leaves their thought processes, nature, etc, fundamentally unaltered, but engenders a complete lack of a desire to leave the Spelljammer and a protectiveness that prompts them to fight off attackers or otherwise see to serious threats to the ship. Once removed from the Spelljammer's air envelope, this effect wears off in 2-12 hours. Of course, first you have to get them off, which is the tricky part.
MacGuffin Title: While a "spelljammer" is a genetic name for a ship([I Am Not Shazam among other things]]), the setting is named after the Spelljammer, a legendary, sentient ship that everyone in the setting dreams of finding and commanding. Whoever succeeds will gain unimaginable power.
MacGyvering: Nearly everything ever made by tinker gnomes.
Magitek: Crops up here and there, with the likes of Autognomes (whose malfunctions can be either hilarious or horrifying), and Clockwork Horrors, a race of mechanical spider-like robots that can strip a world of all life over a couple centuries.
Gaeadrelle Goldring, half-kender on the Rock of Bral: I used to think that a lizard was a lizard, you know, but then I saw that there were as many types of them as there are of people like us. I met some trogs once, not very friendly ones at that, and, wow, did they ever stink. It was incredible. Then I met dracons, saurials, sithp'k, and, of course, the wasag, like that little blue guy over there.
The Multiverse: The characters travel between Crystal Spheres, each containing a solar system or some variant thereof. Basically, every non-scientific legend of what the stars and planets are wind up being literally true in at least one crystal sphere. Additionally, Spelljammer took place within the greater multiverse featured in Planescape.
Our Elves Are Better: The Imperial Elven Navy was a vast but loose empire of elves made up of almost every known subrace from many D&D settings. The IEN was a sovereign entity with its own leadership, but it kept groundling elf nations in touch with each other.
The Spacefaring Elves had the unpleasant characteristics of their landbound cousins turned up to eleven. They were haughty, aloof, snobbish and though of everyone else as semi-civilized smelly yokels. They were supposed to play the role that the Spanish/British Navy do play in swashbuckling fiction.
Rozloom: Please, Captain, you see before you a man in great danger.
They were the result of goblinkind races being almost totally expunged from the spelljamming space by the Elven Armadas and hence recurring to strict discipline and regimentation to make a comeback — Roaring Rampage of Revenge, literally. Some of them learned to speak Elvish well just so they could properly tell the elves who was killing them. The comeback of the Scro formed the centerpiece of early editions of Spelljammer, with adventures including death star-like Scro stations which looked like Gamera and the "good" races of the setting having to put aside differences to fight the common threat.
Our Monsters Are Different: There were whole new manuals about D&D species adapted to "Wildspace", and a few unique to the setting.
Mindflayers and Beholders, already moderately popular in normal settings, were elevated to new heights of villanous complexity, while the Neogi, a cross between a moray eel and a goat-sized tarantula were introduced to serve as reavers and slave traders.
Powered by a Forsaken Child: Death Helms or Lifejammers tap the life force of living beings to power vessels. Employed by Neogi and other evil spacefaring races.
Say What? There IS a planet full of giant lizards which are treated as the Tarrasque. EVERY. ONE. OF. THEM. And did I mention said planet is full of them?
The good news is that they're completely docile lithovores... as long as they stay on that planet. It's suggested that the more familiar versions of the Tarrasque are what happen when they're relocated to other worlds, with atmospheres that don't keep them from going homicidally insane.
Short Range Shotgun: Jettisons, special anti-personnel weapons that fire slow clouds of debris. A good thing to use on pursuers ready for boarding, but useless in long range combat.
Shout-Out: Dolphin◊: the ship with a detachable shuttle on top of an extended curved "neck"? Hmm, what this strange construction could resemble?..
The Rock of Bral is a shout out to Cosmic Boy from the Legion of Super-Heroes, whose real name is Rokk Krinn of Braal. This in-joke was almost almost certainly done because of Rokk's last name being the same as the name of the Dragonlance planet, Krynn.
Space Whale: Not to mention space dolphins and space sharks and an echinoderm or whatever those Esthetics are. And the eponymous Space Manta Ray.
and giant space hamsters
And Space Dinosaurs because why not?
SpaceX: Many variant monsters. The best known would likely be "giant space hamster" thanks to the nod in Baldur's Gate.
Unit Confusion: More than a whole army of umber hulks could make. Those "space tons", dagnabbit. In one sourcebook a mass of 1 ton allows an atmosphere of 100 cu.yd. of air, in another it means body's own displacement of 100 cu.yd., so...
There are mentions of beholders building a giantic weapon resembling an eye the size of a small moon. This eye was capable of destroying entire worlds...
Weird Science: The gnomes! Who happen to be a branch of the tinker gnomes from Dragonlance who found a way into space but never found a way back down...
What Measure Is a Non-Human?: Most humans—except Xenos, the club for rabid xenophobes—resigned such worries facing Loads and Loads of Races. Usually it's "What Measure Is A Non Elf": not only they remained true to their habits, but the strong fleet allows them to feel superior (and be asses about this) even more than usual.
bionoid: Because we are living beings and not intelligent, undead weapons, the elves consider us a mistake. Elves, as a rule, prefer not to acknowledge their mistakes.
A Wizard Did It: The setting runs on this trope. As one source book put it, "It's magic, and it knows it's magic."
World Shapes: All and any. Mostly, planets in solar systems, but even these got tons of quirks.
The specific stories and accesories contain the following:
Clingy Macguffin: The Cloak that Teldin Moore gets at the beginning of The Cloakmaster Cycle.
Cool Horse: Comet steeds. A timid herbivore (after all, they would need to fight only something they can't outrun). Rather smart—for a horse. Trails sparkles. Fast enough to make interplanetary travel practicable (only 1 point below Ol' Manta herself).
