Atris is a white-haired female Jedi Master from the video game Star Wars: Knights of the Old Republic II: The Sith Lords. She is one of the few surviving Jedi, most of the rest having fallen to Sith assassins, and also to a mysterious force hunting all Jedi. She has taken refuge under a polar ice cap on the planet Telos, where she has hidden most of the Jedi's valuable artifacts and resources, such as Sith Holocrons. She sought to remedy what she saw as a fundamental flaw of the Jedi Order: the lack of any mechanism to prevent Jedi from falling to the Dark Side, and repeatedly wreaking havoc on the galaxy. To that end, she trained a group of half-sisters, specially equipped and trained to resist Force powers and if necessary use their Echani combat skills to subdue wayward Jedi. It was possible in Knights of the Old Republic 2 to have one of these Handmaidens in your party.
In the game, if the main character (the Exile) is set as a male, some discussion withe the Handmaiden (the one in the Exile's party) reveals that in fact, Atris may have harboured feelings for the Exile, and the Exile's decision to leave the Order for the Mandalorian Wars was in fact the trigger for her eventual fall to the dark side.
Atris would eventually clash with the Exile, and fall, having been corrupted by power, arrogance, and the Sith Holocrons she safeguarded.
