The single-chamber legislative body of the Lost Tribe of Sith was known as the Circle of Lords. From the Circle Chambers, a room situated near the summit of the capitol building in the capital city of Tahv on the planet Kesh, the Circle held dominion. A Grand Lord, along with seven High Lords, and thirteen Lords presided over the Circle. Although they did not officially have a position within the Circle, Sith Masters were also known to be in attendance at meetings. Darish Vol held the title of Grand Lord of the Circle as of 41 ABY. Lady Olaris Rhea, who commanded the strike team dispatched to attack Luke Skywalker in 43 ABY, was another influential member.
