Tresycht

Treschyt was a country on the planet Essowyn, controlled by High Priest Gellack. The Messert Mines Corporation entered an agreement with Treschyt to mine the Thergum Pits, an area that was in dispute between Treschyt and a rival nation, Yiszte. Messert provided equipment and security forces to Treschyt, and within weeks, the nation of Yiszte had been subjugated. Within four years, the entire planet was under the control of Tresycht's High Priest, Gellack.
