Cosmos

undefined:

A cosmos is a series of layers, (inner)worlds, or gateways connected via direct but non-physical/literal connections. Travel may be easier between worlds connected as part of a cosmos than worlds that are not. Distinct from a metalayer in that the worlds are not physically connected or in the same literal space - there is no way to travel from one to another except via teleportation.
