Shadow Assassins

The Shadow Assassins were a group of Sith Assassins who resided in a secret Sith Temple on Umbara. They were originally founded by Darth Ruin as part of the, but after the fall of the Brotherhood of Darkness, the surviving Shadow Assassins went into hiding. They remained in hiding for many generations, with no outside contact until Darth Massikus and Talzin came to the Temple for a time. While they were there, a team of including Ganner Slarwalker discovered the Temple. Though Ganner was captured, the others escaped, and the hunt to stop them from returning to the Jedi began the Shadow Conflict. Ultimately, the Shadow Assassins were totally purged at the conclusion of the Shadow Conflict due to Eclipse Protocol killing many assassins, and Ganner Slarwalker dispatching the rest.
