Sergei was raised on the outskirts of Novygrad by his mother and father. He belonged to a poor family but a thriving community outside the city. His father taught him all he needed to know to survive off the land from hunting to farming nothing was left unlearned. When Sergei turned 11 he began to work on a farm in Kabanino where he tended livestock and acquired a plethora amount of knowledge about hard work and dedication at a very young age.
When Sergei turned 15 he met a girl named Anna from Austria. She was adopted by a wealthy family in Novy Sobor when she was 2. They fell in love and worked together on the farm tending the cattle and herding the sheep. One day, Sergei took Anna to see the dam near Pustoshka. They climbed in an old VW and set towards the southwest. On the way, Sergei failed to yield to a pickup truck and took a shot to the passenger side door. Anna was killed instantly and Sergei suffered memory loss with a deep laceration across the chest from a large shard of glass. Sergei made a full recovery and still recollects memory of Anna moments before the crash.
2 years later Sergei joined the Chernarussian police force. There he adopted several skills in mixed martial arts and firearms training. He spent 20 years in the police force. After his retirement he settled in a comfy log cabin in Lopatino. There he collected a nice pension from the government and a steady income in wheat production.
6 years later an infection breaks out wiping the local population and causing a rupture of panic throughout South Zagoria. Sergei took his duffle and shoved everything he needed from the local grocery store and wrapped an AKM to his side and headed for the eastern hills of Grishino where the infection was less present.
