Multiverse

The Calamity Multiverse is the multiverse in which this narrative story exists. Within the Calamity Multiverse, several universes exist, which can all have their own laws of physics, and have no relation to other universes. Within universes are an infinite number of fifth-dimensional dimensions, which are divided into two types; dimensional planes and extra-dimensional planes. Dimensional planes have the same set of physical laws governed by their parent universe and usually deviate only slightly from their siblings; extra-dimensional planes may have any physical laws, and include pocket dimensions.
