Neh-Thalggu

“Something was creeping and creeping and waiting to be seen and felt and heard.”
  Neh-Thalggu is an aberration that resembles a crab-like creature with a lamprey mouth, twitching eyes on its legs, and several blisters along its back that hold human brains. Embryos of the creature are somehow placed or implanted in a victim's head where they remain until they burst free. Victim's typically show the Sign of Gha after they have been infected. Newly birthed neh-thalggus, which horrifically kill their host upon eruption, are capable of Common speech and are immediately dangerous. The Fellowship encountered embryos within the town of Ravengro. A full adult version was accidentally summoned by the werewolf followers of Jezelda in the Shudderwood.
