Therum (formerly known as Nexi Hallah to the protheans, Colony Y to the Zeioph and Jrefa Rreft to the Tatha Navaria) is the second planet of the Knossos system in the Artemis Tau cluster. Before the Reaper War, Therum was a Systems Alliance colony, but became a Systems Coalition colony and, later, a Galactic Dominion colony, following the war.
