Gith

In the Dungeons & Dragons fantasy role-playing game, Gith is the fictional liberator of the race that would become the githyanki and githzerai. Largely absent, her role is one of a legendary figure of myth rather than an active player in the game's fictional universe (though some published adventures, such as the fourth edition Scales of War adventures, feature her a in more active role). In the chronology of the game, Gith freed her race from slavery at the hands of the Illithids, and then sacrificed her own freedom and life for the ensured survival of her newly-freed people, thus cementing her as a recurring motif in githyanki-based adventures.
