Neh-thalggus are crablike nightmare with lamprey-like mouths, twitching eyes on its legs, and several blisters along its back that hold human brains. Some speculate that neh-thalggus encountered in this reality may merely be juveniles of their kind, perhaps exiled from their home worlds by greater kin until they can prove their worth on other worlds. \n'b'  Brain Collectors . Neh-thalggus are carnivores, but they do not digest humanoid brains they eat\xc3\xaf\xc2\xbf\xc2\xbdrather, these brains lodge in one of several bulbous blisters on the creature\xc3\xaf\xc2\xbf\xc2\xbds back and help to increase its intellect. Their brain collections may be a morbid form of currency in their home realm, or the thoughts in these brains may merely be fuel for a dark apotheosis into an even more sinister mature form. \n'b'  Mind Masters . Neh-thalggu masters lord it over their lesser kin by applying the drained brainpower of their victims toward mastering psychic magic and mesmerism. They may inhabit elaborate mindscapes as their lairs or may subtly influence the thoughts and senses of creatures they lure into their lair in furtherance of convoluted plots to manipulate the societies around them while they dwell in secret. Some dwell alone or with mind-controlled slaves, while others organize clusters of their own kind to spread their sinister schemes and feed their insatiable alien hunger.'
