Stegocentipedes are rumored among sages to have come to the Material Plane from another plane or dimension, though no proof has been found to support this theory. Whatever their origin, they are greatly feared by adventurers and other dungeon dwelling denizens for their poisonous bite and sting. A stegocentipede raises its spines instinctively when it enters combat and rushes its prey. Opponents are bitten and stung to death.
A typical stegocentipede is 18 feet long. A stegocentipede ranges in color from brown to green.
