Markus grew up in an secluded area with only an abusive, drunken father as family who besides beating Markus frequently only ever taught him the craft of hunting and survival.
Prone to being by himself and nature he never really managed to hold down any relationships or jobs throughout his life. Sticking to living out in the woods, where he feels at home.
Markus is a calm, quiet and collective person who while on the outside might seem nice has a deep, hidden, unreleased rage that has been building up throughout his entire life and a despisement towards mankind as a whole. Seeing the end of the world almost as karma for how mankind has treated earth and eachother.
Having survived on a ship with a group of survivors arriving towards Chernarous eastern shores, he keenly volunteered to join the scouting party heading there in a lifeboat to be able to wander about on solid ground again.
Didn't take long for the party to get swarmed and Markus soon found himself to be the sole survivor and forced to retreat inland. Managing to find his way to the coast again at a later stage the ship was gone and he has been wandering ever since...
