Void Clouds

The Void Clouds were a void-borne species said to have existed right after the creation of the universe.

Biology
The Void Clouds are sentient "objects" formed by pure and raw energy that was present during the Big Bang. Most species that encounter them can't put them into words. Most see Void clouds as awe inspiring. There is a theory that the Void Clouds are in fact just multiple branches of one sub space entity.
