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.
