Seems to store brains on body and use them for knowledge and power. Can extract brains from creatures.

Known also as brain collectors, the alien neh-thalggus hail from distant worlds, traveling the gulfs of multiworlds. They are known to travel on immense living ships that swiftly decay when they arrive upon a new plane, leaving behind a deadly cargo of hungry monsters. Neh-thalggus are carnivores, but they do not digest humanoid brains they eat—rather, these brains lodge in one of several bulbous blisters on the creature’s back and help to increase its intellect.

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. 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.
