Myo was a vicious Abyssin scout who was a native of the desert planet Byss in the Outer Rim Territories. As a youth, he proved himself to be a fearless warrior, surviving three tribal Bloodings on his homeworld. He lived most of his life in isolation from his fellow Abyssin after being captured by a Rodian slaver named Malak and taken off-world. Myo was able to escape his captor while her starship was refueling at Kinun Depot, however, and eventually befriended the Bith musician Lirin Car'n, who provided him with passage to the arid world of Tatooine.
