Markus was a Private in the U.S. Army. He was a combat medic with a passion to help. He enlisted in 2015 and was honorably discharged in 2016 for a PSTD attack that came from killing a Syrian child, from that point on he is terrified of firearms and will never use one. He has vowed to never take a life, unless it was to defend an innocent person. His medical experience has only grown from his time in the Army. He found his way to Chenarus after he realized he could make a difference in the hospitals there.
