The Metavasis was an ancient research vessel created by the extinct Kathol over one million years before the Extant War. Believed to have potentially been the source of phase engine technology redeveloped by the Charon of the Second Charon Dominion, the Metavasis was a mobile laboratory utilized by the Kathol in dimensional experimentation, through which the Kathol inadvertently discovered Otherspace galaxy and the rouge planet of Otherworld.
