Krystof was born and raised in Novigrad by a Father who served in the military and his mother keeping the home-front in the best manner she could do, and what they could afford. Despite Novigrad being the capitol of Chernarus and one of the wealthier town there was still people struggling on the outskirts of the city.
After his father died in the war and his mother succumbing to her grief in a mental institute he was "adopted" by a motorcycle gang he had been around before, at this point he had dropped out of school and started his passion for bikes. He would do some small repair jobs on private to ensure that he would have enough money for fuel and food for another day, but would sometimes burglarize a house or two to get that extra cash he needed.
Krystof ended up in South Zagoria when they were out on a coast to coast ride when the infection hit, they ran into a huge herd of infected along the coast line and got separated most of them presumed dead.
