Treschyt, a nation governed by the High Priest Gellack, was situated on the world of Essowyn. The Messert Mines Corporation forged a pact with Treschyt for the exploitation of the Thergum Pits, a territory contested by Treschyt and the opposing country of Yiszte. Supplying Treschyt with both resources and protection, Messert facilitated the swift defeat of Yiszte in a matter of weeks. A mere four years later, High Priest Gellack of Treschyt had extended his dominion over the entirety of the planet.
