Chaos Spawn

A Chaos Spawn is a mindless mutant creature who once belonged to one of the intelligent races of the galaxy and who has become so mutated through their servitude to Chaos that they devolved into a twisted and insane abomination. Those seeking immortality and power through the ultimate attainment of daemonhood in service to the Ruinous Powers face the constant possibility of being reduced to Chaos Spawn, either by accumulating too many mutations or being cast aside by their Chaos patrons as unworthy of further advancement because of their consistent failure to serve the will of the Chaos Gods.
