Destroyed by Infested Stukov's mercenaries
The "Vermin" consisted of the Kimeran Pirates, a group of protoss fighting alongside mercenary archon Mertick the Mauler and a group of zerg fighting alongside "mercenary" mutalisk Cardis the Destroyer.
The groups took shelter on a dark planet, but Stukov tracked them. He hired a selection of mercenaries to fight and destroy them. The "Detestable Vermin" were destroyed.
