On the Edge of the Empire
He was formerly a Commander of an Imperial regiment and identified by his skull-sculpted trooper helmet. His heritage, however, was Mandalorian, and he was conscripted during the Clone Wars into what eventually became the Galactic Empire. He served well as a trooper and rose through the ranks; however, he often butted personalities with Moffs and other leaders of humancentric ideals.
Then his squad received orders that ultimately stranded them on the noxious junk planet Raxus Prime. Without a real war to fight, he chose to remain there … where they stayed for many years … that was until the ragtag crew of the Solace convinced him otherwise.
