Among the largest of the Wormbrains, Paraslob begin life as exceptionally large Paraseethe and eventually lose any remnant of their own nervous system as it is consumed and replaced entirely by brain flukes. Though they have difficulty moving, these monstrosities generate the farthest-reaching psychic lure of the telepathic wormbrains, attracting new hosts from far beyond their territory. They guide living beings straight into their cavernous gullets, regurgitating them as worm-ridden drones.
