Kaleb Valdemar's Body

Intellect devourers serve as advance scouts and infiltrators for the powerful force of alien beings called the Dominion of the Black. These monsters roam the Darklands, from which they mount secret invasions of the world above. When an intellect devourer infiltrates a society, its first priority is to acquire a body. It might first seek out a graveyard for a fresh corpse, as this is easier than fighting and killing someone. When the aberration compresses itself into the host's brain cavity, its real body goes dull to sensation as it connects to the nervous system of its host. If found out, an intellect devourer might quickly inhabit a new body to make its escape, preferably something inconspicuous such as a domestic animal.
