Neuroflies are a type of magical creature found in the jungles of the Spine. These giant mosquito-like beasts drain not blood but rather memories and intellect, leaving their victims in a stupor. The neuroflies seemingly learn from doing so, temporarily acting with more cunning and seeming to possess knowledge of things of which they were not previously aware, before eventually returning to their more animal-like state.
Neuroflies are easily distinguished from the other giant mosquitoes of the Spine by their bright blue eyes and their tendency to avoid swarming, preferring instead to act as ambush predators.
