Responding to the distress signal of a Galactic Republic starship that had crashed on Athiss, a Jedi team came to the planet. Each member was attacked by a Sith devotee. One was slain by Chamma, though he gave in to the dark side of the Force, after which the other two fled.
During the Cold War, Athiss was the site of a mysterious cult devoted to Vodal Kressh, a powerful Sith Lord who once challenged the Sith Emperor. A team of operatives was dispatched to the planet to investigate.
