Spine Slug

The Spine Slug was a parasitic creature that lived on a Skakdi's spines. They possessed the ability to feed of a Skakdi's rage, although how they did this is unknown. Some theorize the Spine Slug was actually capable of influencing a Skakdi's anger to gain more nourishment, but no Skakdi would ever admit that such a thing was true. Skakdi also never did anything about the slugs, because if they did stimulate rage, it could cost them an edge in battle.
