Among the very few places on the Jungle Planet not firmly under the control of Scourge are the fetid swamps in the valleys at the foot of the Steel Shard Mountains. Here, Repugnus rules. His subjects rejoice in the sinking slime they call home. He protects their freedom fiercely, using his intimate knowledge of the swamps to isolate and destroy any invaders. So dedicated is he to freedom that he even exiled his own brother - Undermine - for being in league with Scourge.
