Sith'ika was an ancient Sith holy world deep within the Unknown Regions. The planet's religious significance was deep seated, being older than the Sith Order of Decreto. Shortly before his death in 3,820 BBY, Ater Phasas'a, knowing something that all Dark Lords of the Decreton Empire since did not, built a temple on the planet, in Sith'ika City. It was chosen by Darth Krayt to be the resting place for the holocrons of Sam Sinays and Ater Phasas'a after their discovery.
