The Tal'adin Republic was the largest Sa'ari nation-state on T'lessia. Its capital, Tal'adin City, was the location of the headquarters of the Order of the Blue Light and the seat of the planetary government. Though it was the largest nation in terms of land area and population, at the time of the arrival of Laera Reyolé and Silas Dan'kre, the so-called "Starborne Ones", its political power was secondary to that wielded by the Hiltone Republic's coalition.
