Sir Eihwaz SO was a Massassi soldier of the Royal Army of the Golden Empire. Born on Abstalia in the early months of the Great Liberation, Eihwaz was raised and trained for war in service to Rin Sakaros, like all Massassi. In 116 ABY, he relocated along with the rest of his species to Kavez Massass. In service to the Royal Army, Eihwaz was assigned to several different Massassi Cohorts, distinguishing himself enough that at some point he earned a spot in the elite 11th Massassi Cohort. He was given an officer's commission and by 149 ABY was the colonel in charge of the entire Cohort.
