Hermes

The story of the planet Hermes is, perhaps, the story of the greatest cruelties of the Overlords. The planet is home to evolutionary adapted settlers who can breathe the poisonous atmosphere of the planet because of generations of natural selection on the planet's surface.

Preacher believed that the natural immunity of the citizens of Hermes may hold the key to defeating the unknown threat the galaxy would soon be facing. After peaceful rebellion of the planet's citizens at the start of the Galactic Civil War. Preacher subjugated them, horribly experimenting on all of the rebels, until they became disfigured and eventually died. There are few planets in the galaxy who despise the Overlords as much as Hermes.
