Fascinated with firearms since first laying eyes on his grandfather's hunting rifle, Sixten is an enthusiast and collector of guns. He was a member of a shooting club but otherwise untrained in terms of military service. He has survival skills thanks to his grandfather who taught him about forests, woodlands and wildlife. Sixten travelled to South Zagoria for pleasure, to see and try old Soviet weapons, but got stuck in the chaos instead. He survived the early days by tagging along those who found his skills with firearms useful, and didn't think twice when he used them against anyone in his way.
