The Ascendance Conflict was a two-year span of the New Mandalorian Wars that saw the Tair Republic face the Sith Ascendancy in open war on numerous worlds. The Sith were crippled after the Potentate, Darth Vician, was captured in a duel on Onderon with Jedi Master Ta'Ri and the Jedi Knight Sil Sentarra, and finally pushed back into Wild Space and the Rishi Maze beyond. Although not entirely eliminated nor ever officially defeated, the Ascendancy reorganized as the Shadow Empire and was never a tangible threat thereafter.
