Nerve Larvae are a dendritic colonial microorganism. Tiny threadlike structures and spinning "star-tails" help propel them through the waters of the host's brain's brood chambers. They swim over the course of their 2-3 day short lives to the host extremities paralyzing their nervous system functions and spawn on the way back. When Nerve-Larvae decease over many generations their husks create a coral-like buildup swelling the victims brain and giving the skull a lumpy appearance resulting finally in death.
