Can someone explain the unified D&D cosmology? I understand some things within individual setting, like what planes Greyhawk has, but I have no idea where Planescape fits in and how the hell Spelljammer works and stuff like that.
D&D Official Cosmology

Once upon a fucking time the universe was made by two dragon sibling sucking their dicks.
One was a rainbow scaled neon-dicked futa dragon, and the other was her red-skinned tinier bottom bitch cuck brother, and they spun whilst doing this nasty-ass dragon 69 and created the laws of the universe whilst there was like, jack shit but the astral sea.
Then the fucking Great Old ones passed through, did some fission, and the Astral Sea was Space in this universe, so Yog-sothoth was on the Astral sea partially visible and stuff, but then at some point Shub-niggurath showed up, is some Fission and made Aboleths.
Actually fuck it, the Great Old ones were always involved, but during the time of this cosmic cock-suck they got kicked out because an Aboleth pulled a Prometheus or some shit and it hit the astral sea, making the Divine Spark which made deities in response to the maddened collective calls of bedlam and distress various races had due to being in Will save SAN check hell or some shit.
And before this Dragon Pre-deity entity and Outergod/Great Old one crap was going on, the entire plot of Shin Megami Tensei III: Nocturne literally occurred and somehow this mixed up with so much shit with the Red cuck dragon, he fell to the lower planes in what was to be hell, hit the 8th layer, making the 9th, and remained there ever since, brooding, and eating fedoracore souls, and was involved in that Ashradorn shit if you read into the context.
And that's why it's called dungeons and Dragons.
Also, the Great Old ones sort of got kicked out, and are trying to get back in via proxies and memetic bullshit and stuff, but that's a while to go yet, because the warhammer 40k chaos gos are also making their way in.
It's a melting pot universe of planar shit from other universes in it's own bizzare metaphysical orbit because we never went to space and the earth is kinda flat and hollow but not flat flat.

Planescape uses the Great Wheel which divides the Multiverse into three major parts, the Inner Planes which are planes of matter and energy where Elementals and such live, the Outer Planes of emotion and thought which correspond roughly to the alignment chart and are where the Gods and Demon live and souls of mortals go after death, and finally the Prime Material Plane which is the physical universe of mortals.
Spelljammer is a way to allow players to cross from one setting to another without leaving the material plane and is basically fantasy space travel.
Nathaniel Barnes
Anyway to elaborate Planescape is a setting designed for PCs to explore the Great Wheel. The PCs are usually based out of Sigil which is the city at the center of the multiverse controlled by an entity called the Lady of Pain. The city itself is run by several factions each with their own philosophy on the Planes and is set against the backdrop of the Blood War which is a millennia old conflict across the Outer Planes between the Demons of the Abyss and the Devils of Hell.
Spelljammer is a setting set entirely on the Prime Material plane. It's space travel, but space travel based on 19th century science and fantasy. In it each solar system is encased inside of indestructible crystal spheres, between the spheres is a substance known as phlogostom that special vessels can sail through to reach other systems. The primary vessel runs on magic and is called a spelljammer.
Each Crystal sphere is under the influence of an Overdeity who determines how the rules in that sphere work and also which Gods can access it. This is how vastly different settings like Toril and Oerth can coexist in it.

> Planescape
This is the largest-scale "setting". Basic conceit, there are many dimensions (Planes) that exist. The Inner Planes embody the primal elements of creation. Air, Fire, Water, that sort of stuff. The Outer Planes exemplify belief and concepts like good, evil, and various philosophies. The Material Plane consists of physical worlds governed by what we would generally think of as natural law. (According to Planescape, the various campaign settings like Greyhawk and Forgotten realms exist as material planes or "Primes") The Transitive planes bridge the gaps (Astral between Material and Outer, Ethereal between Material and Inner, and "Nobody can get there to confirm what it's like but by magic science we know it, like dark matter, must exist" Ordial between Outer and Inner)
Most Planescape campaigns take place on the Outer planes, at least nominally. These are realities that function as heavens and hells. The gods make their home there. The souls of the dead appear there. And a bunch of living folks like you also call it home.
The best detailed setting in the lot, though, isn't really one of the "Planes of Belief". It's Sigil, aka the City of Doors, aka The Cage, aka a city built on the inside of a ring that hovers above the top of a mountain of infinite height. Planescape is esoteric like that. The city is valuable because it has portals to just about everywhere. If you have ANY interest beyond your own plane, Sigil is the way to indulge that interest. It's not a total war zone because its 'ruling' entity, The Lady of Pain, is fairly hands-off and the biggest fish in the multiverse. Basically, she exists to enforce some weird, esoteric setting rules that are about as absolute as gravity though with more human-understandable punishments for trying to violate them.

Da Rules of Sigil
>Don't fuck with Sigil as a whole
>Don't fuck with the Daubus that maintain the place.
>Don't fuck with the Portals
>Don't worship The Lady of Pain
>Don't worship Aoskar. (He's dead anyway.)
>No Gods Allowed in the City (Seriously, Lady of Pain will fuck up puny gods.)
>Seriously, guys, your infighting is mucking things up. You get fifteen flags/factions, tops
After an end of 2e extravaganza module/event called the "Faction War"
>No more goddamn flags, Factions get out reeeeeee
and
>*Mutters some other stuff GMs can mine for plot hooks*
The Factions, mentioned earlier, are/were the mortal scale movers and shakers of Sigil... and beyond: while they all want influence in Sigil they have and maintain interests in other planes, mostly the Outer though some will mess with the Inner or Material planes. Factions are distinct by their philosophies and in a surprising case of grey and grey morality in a world with LITERAL good and evil as present forces, any one of them could be a group the PCs join or your villains for the evening
Dylan Martinez
Factions are...
>Fraternity of Order believe in math and law and keeping everything tidy. They run the courts in Sigil
>Harmonium are Lawful "Good" Totalitarians who believe they'll make utopia when and only when everybody follows their way of life. They're standard cops. They're kind of assholes (more than most factions)
>Mercykillers believe in the punishment of wrongdoers above all else. They run the prisons and are the psycho judge dredd cops.
>Dustmen are weird psuedo-bhuddists who believe we're all already dead and the suffering of "life" means that we should strive to attain the peace of True Death by purging ourselves of all emotions. They run the mortuary
>Sensates believe in experiencing every possible sensation. They run the entertainment industry in basically all its forms
>Bleak Cabal believe the universe is inherently meaningless, so they're basically nihilists. They're nice nihilists, though, and run the soup kitchens and asylum because hey, if there's no meaning to anything, why not make the world a little better? They kind of inevitably go crazy though.
>Doomguard believe entropy is increasing and that's about all they agree on. Most want to help along the decay of everything, though, and they make weapons and handle the armory
>Fated believe that might makes right and if you can take something and keep it you deserve to have it. They are tax collectors, thieves, and general assholes. Not a bad faction for murderhobos though.
>Sign of One are solipsists. Each one of them believes that they are the center of the multiverse and everything else is their imagination. Since Belief in planescape has real effects, they can kind of warp reality like that. Predictably, they keep government running.
Aaron Ortiz
>Believers of the Source (Godsmen) believe that all souls are on a journey to eventually ascend to godhood and want to self-actualize. They run forges and do lots of crafts
>Athar believe that the gods are frauds not worthy of worship. They mostly just hide here in Sigil because of that No Gods Allowed rule.
>Transcendent Order believe in doing, not thinking. They act on instinct but tend to gain spidey senses.
>Free League are a faction of not caring about being a faction. Loose and informal, their 'uniting' philosophy is free will. They kind of control the markets and bazaar
>Revolutionary League believe that the power structure is corrupt. They want to tear it all down and bring the other factions to ruin. Nobody is openly Revolutionary League, they infiltrate other factions with sleeper cells then cause havoc.
>Xaositects believe in Lolrandumb chaos.

>Spelljammer
Spelljammer, like Planescape, is an "oversetting". It actually exists within Planescape and covers the Material Plane. In Spelljammer, the Material Plane, which contains all the 'normal' campaign settings among other things, is explained to exists as sets of Crystal Spheres (Generally, Solar Systems. Campaign Worlds like Faerun and Krynn each get their own, but other Systems may have multiple habitable bodies) Spelljamming ships are space flying sailing ships that can traverse Wildspace and the Phlogiston (Existing inside/outside Crystal Spheres) to go places and visit other worlds.
It's basically a weird, fantastical space opera that Treasure Planet mined for its look and feel. Except Spelljammer is weirder. That's kind of rule 1 of Spelljammer when compared to anything except the most esoteric corners of Planescape. Spelljammer is weirder. There are gnomish ships powered by giant space hamsters running in (paddle)wheels, Nazi Elves at war with non-retarded Klingon Orcs, pirate monkeys, hippo men, like three flavors of mercantile assholes including the Neogi, and the legendary ship simply called the Spelljammer is shaped like a giant manta ray with a city on its back and might be alive/intelligent.
