Susverses are verses that are very close to voids with the only thing they contain as a single identical copy of universeverse in the very center. Some advanced civilizations tried to explore Susverses but abandoned their ships and probes in the void because of nothing being there, so susverses are full of abandoned ships and junk.
The only permanent life in susverses is the microscopic nulls present in almost all verses, as well as the crewmates and impostors which float on huge colonies of nulls, junk, or in abandoned ships to avoid falling into the void. Impostors are predators which are able to eat crewmates very easily because impostors appear as pitch black, like the susverse itself, giving them extremely powerful camouflage ability, although they cannot exterminate the crewmate population because there is almost infinite numbers of crewmates living in a susverse because of its size. Some impostors also started breaking into the abandoned ships and sabotaging and killing crewmates in there.
