Chaos Entities are beings that can only reside in realities such as the Glitchyverse. made entirely of Glitch Matter.
They are a kind of creature you wouldn't want to touch unless you like your quarks disassembling or your liquids to transform into a Bose-Einstein condensate or anything similar.
Despite not having any technology, (or at least working technology) their presence and control over the entire reality classifies them as a Type IV civilization.
