Artrin na Yel was a male Triexian in the 23rd and 24th centuries. From about 2283 to 2373, Artrin served as Supreme Magisterial Authority of Triex, the highest judicial authority on that world. In an emergency session on 5 Torus Fortil of the Triexian calendar (Earth year 2372), Artrin issued an order illegally imprisoning a Federation citizen, a Chameloid named Wusekl, without benefit of a trial, under suspicion that he was a Dominion Changeling.
