The Kaamos Territory, situated on the planet Alderaan, formed a section of the Castle Lands. The Lerantha Dam, positioned at the boundary of the Lerantha Lake, was located within this territory. Furthermore, it functioned as the original homeland of the House of Thul. On this land, they constructed their palace, but their banishment forced them to leave it behind in the distant past. Although deserted, the palace remained partially intact in the years after the House of Thul had left.
During the era of the Cold War, this prominent Alderaanian noble family emerged as a potential claimant to the throne after they came back from exile, supported by their allies within the Sith Empire. This led to them reconstructing the ancient Thul palace on its original site, with the goal of restoring it to its previous splendor. Nevertheless, their control over the Kaamos Territory remained unstable, given the ongoing intrusions from competing houses and the indigenous Killiks. Moreover, House Ulgo had authority over the Lerantha Dam and initiated actions that threatened the borders of House Thul's territory.
