Planes of Existence

The infinite layers of the abyss count upwards from the bottom first layer, the Layer of the Abyssal Seed, and is the embodiment of pure Chaotic Evil and spawns endless hordes of demons to corrupt other planes and bring them under its influence.

The howling caves of Pandemonium are filled with fiends and monstrosities that eat whoever happens to stumble into their locked plane. Considered a prison plane, entering is easy, but escaping its accursed depths is nigh impossible. It lies between Chaotic Evil and Chaotic Neutral.

Limbo is the plane of pure chaos. Matter has no set form, changing from dirt, to diamond, to water, to plasma, to a tree, and then dispersing and reforming elsewhere. The only thing set is a creature's will, and those with strong minds can mold it to their will. The embodiment of Chaotic Neutral.

Ysgard, the plane between Chaotic Good and Chaotic Neutral, is heavily inspired by Norse deities. The giants hail from this plane, and is where they go for their afterlife. The giant deities reside here besides Annam, the all-father.

Arborea/Arvandor is the plane that is considered holy to elves, as it is where their pantheon resides, and where they will eventually pass on to after they achieve Correlon's blessing. Until they, they are to reincarnate and remember their past lives.

The place animal spirits head to upon death is known as the Beastlands, and it is also where lycanthropes and beastfolk souls go upon dying. Alignment is between Neutral Good and Chaotic Good.

Elysium is the neutral good plane that is the hub for all good aligned deities, as well as celestials and other divine situations. Ruled by the deity Mariata, Queen of Patronage who focuses on life, and is married to Kelemvor.

The plane of Bitopia had a strange effect on itself. It was a massive plane that had folded in on itself, with gravity functioning normally on both sides, but if you looked up on one plane you would see the other directly above you, and passing the halfway points between the 2 planes would cause it to shift to the other side's gravity. This plane is ruled by the Bitopia pantheon, also based on the Faerun pantheon. Its alignment lies between Neutral Good and Lawful Good.

Mount Celestia Is the plane of absolute law and good, and is ruled by the Celestia pantheon, which is heavily inspired by the Greek pantheon. It has 7 holy mountains, all subsections of the same super-mountain, and the plane itself removes evil intentions the higher up you climb.

Arcadia is the plane between Mount Celestia and Mechanus, and is a plane of serene plains dotted with small mountains. The dwarven, gnomish, and halfling pantheons all claim their own layers here. Its tendencies align it between Lawful Good and Lawful Neutral.

The plane of gears and constructs is known as Mechanus and is mostly inhabited by modrons, golems, and select few human colonizers, all of it ruled by the deity Primus. The embodiment of pure law, Primus and his plane are a haven from the chaos of other planes.

Acheron is a plane of eternal war, where dying one day means you are revived exactly 24 hours later to continue fighting. 4 enormous cubes make up its layers, continuously crashing into each other as armies swarm over their surfaces. Orcs and Goblins that serve Gruumsh and Maglubyet respectively have their souls sent here.

The Nine Hells, the embodiment of Lawful Evil to the extreme and home plane of the devils, is ruled by Asmodeus and his infernal legions. Bound in an eternal war with the Abyss called the Blood War, the river Styx binds both planes together and forces them into this war.

Gehenna is the plane of deals and contracts. Residing between lawful evil and neutral evil, the Yugoloths that live there form selfish contracts as mercenaries and thugs. Unlike the 9 hells where breaking a contract spells certain destruction, in Gehenna it is merely rude and might get a bounty on your head but not much else. the General of Gehenna rules this plane with an iron fist, rarely showing himself unless absolutely necessary.

Hades is the cousin plane of Gehenna, the embodiment of absolute unadulterated evil. Yugoloths also rule this plane, as well as hags, fiendish Larvae, and lost fiends from other planes.

Carceri is the fiendish plane bordering neutral evil and chaotic evil, and is inhabited by Demodands, nightmares, and Vargouille in its twisted, warped, gravity ignoring arches of stone.

There are also an endless number of Material Echoes that resonate parallel to the material plane, such as an Eberron, Dragonlance, and Dha'oh'hrrok (the latter is homebrew)

Other planes not a part of the Great Wheel are the Fewilds, Shadowfell, Elementals Planes and the elemental chaos, the Ethereal and Astral planes, and the Betweenlands.
