Clagborne Lineage

A peculiar species of subterranean magical ooze, Clagborne are a deeply mysterious race. Unique in that they are fully amorphous and brainless until they find a host, almost nothing is known of a Clagborne’s early life or origin, as even they remember nothing of it.
What is known is that these brainless oozes slime their way through caverns and dungeons on instinct, until they come upon a humanoid corpse. At this point, the Clagborne strips the body of its flesh and tissue, magically absorbing all chemical and electrical information, and is “born” as a new entity, complete with all the memories of its fallen host.
The ooze wraps around the skeleton, forming a new body in the model of the old. A Clagborne can alter the transparency and colour of its slime flesh to suit its wishes.
Although a Clagborne retains the memories their original form had in life and are functionally identical in personality, desires and ability, they are a distinct creature. The soul of the departed does not return to the Clagborne, and many struggle coming to terms with their identity.
Are they the same person as they were in life? Or an abominable walking undead, host to a parasitic, brainless monster?
