Engram Aberrants

An Engram Aberrant is a mutated lifeform born from the fusion of Engram energy and lingering obsessions. It must cling to a physical corpse or specific item to maintain its form.
Commonly known in folklore as "ghosts," "undead," or "spirits",

these beings emerge when strong emotions at death prevent full Bio-Engram dispersal-leaving the spirit linked to Engram energy in a twisted union. Aberrants are surrounded by a natural Engram field, but lacking Bio-Engram, they instinctively attack nearby life to steal it and survive.

Most are mindless echoes of who they once were, but some reports speak of aberrants capable of speech.
