Born half a decade after the fall of communism in Romania, Vadim was the second son of Maria and Ioan Coman, brother of Stefan. Even if at the begining Vadim's family struggled after the fall of communism due to poverty, slowly and especially after the adherence of Romania to the European Union, the family managed to get in a stable financial situation and offer Vadim and Stefan a decent life. Vadim was fascinated by medieval history and mountains, being an active hiker since a young age. After he finished with school he studied statistics and economic informatics at an university in Bucharest.

During the outbreak, Vadim found himself in Chernarus on a summer solo trip around Chernarus to hike around the mountains and visit the medieval castles of Chernarus. When Vadim realised what was really happening in Chernarus, it was already too late. He would never again be able to meet with his family, his friends, or his girlfriend that he had so many plans for the future with. Suddenly everything changed and he is now alone with only one goal, surviving.
