I’ll explain more about Dungeons & Dragons. Dungeons & Dragons hosts a multiverse (the D&D multiverse) consisting of various realms and dimensions. Central to this are the Material Planes, which can be of infinite variety and host countless worlds like the Forgotten Realms/Kara-Tur, Greyhawk, Dragonlance, Eberron, Dark Sun/Athas, Ravenloft, Planescape, Spelljammer, Mystara, Birthright, Al-Qadim, Ghostwalk, Council of Wyrms, Nentir Vale, Exandria, Innistrad, Dominaria, Kaladesh, Zendikar, Amonkhet, Strixhaven, Ixalan, Ravnica, and Theros. Surrounding these are the Inner Planes, representing the elemental forces and consisting of both Elemental and Energy Planes, potentially infinite in their own variations. The multiverse also includes the Outer Planes, which are realms shaped by moral and philosophical ideologies, potentially hosting an infinite number of alternate versions based on the beliefs and actions of their inhabitants. Connecting these realms are the Transitive Planes...
