In the cosmology of Anuwai, different planes exist that function as different dimensions. While many planes share features in common with vanilla D&D lore, the far-future setting of Anuwai means that some of the planes function very differently, are oriented differently, or might be changed to locations within planes rather than their own planes of existence. Almost universally, the cosmological origins of the planes are vastly different from vanilla D&D, and as a result likely have different physics, geographies, inhabitants, politics, etc.
