Bogdan, a well practiced surgeon, was born in Chernaurus in 1969. Being born on a farm wasn't the best homecoming for him as a child, since as young as 6, he was well intellected and wanted to pursue medical jobs and other high-intellectual fields, and was very avid for what was in the future for himself. Working on the farm wasn't stimulating him, and most of his enjoyment was just spent in school since. As soon as he was age after graduating top of his class from primary and second school, he left for the city, enrolling in a medical education. He spent most of his time studying, but also worked part-time in a bar in Elektrozavodsk as a pianist, which he learned his piano skills from a young age from an instructor, at the same time he was living in his families farm. With no doubt to anyone, he worked his blood, sweat and tears into achieving his доктор медицинских наук doctorate, or his Doktor Nauk degree. Achieving a well pay for himself, he was set for life. He practiced for about 2 years in Chernogorsk, until the hospital and one of the highest achieving doctors in Chernaurus recommended him pursuing a field inside a research station in the South Pole due to new health guidelines after a Russian doctor was forced to perform an appendectomy on himself. He was stationed there for 6 years in total, putting forth insurmountable effort, and learning even more skills that contributed to his medical expertise. He was dismissed and sent back promptly after he spent his 6 years there, and went back to live and practice medicine in Chernogorsk. His life was pretty normal, hanging around with friends in bars, minor hooliganism, adventuring Chernaurus, until it happened, when apocalypse set on Earths' doorstep. Bogdan had no idea where the disease came from, but he has some skills in virology to understand what was going on during the outbreak. He watched as the entirety of Chernaurus reigned into disaster before his very eyes, watching hearses bringing in dying or deceased cadavers into research theaters. In weeks, he counted the entire population loss with virologists, counting that the entire population of Chernaurus (3,800,000 people) dropped from it's number down to only ~2,500 people in the matter of again, weeks. However, unknown phenomena occured; corpses began rising from the dead inside morgues and other dead storage, and infected was known to physically attack and lacerate individuals once they sensed individuals. He worked with trying to remove infected tissue as a means of a cure or mitigator, which proved to not work, as the disease appeared to be septic. Using antitoxin for botulism proved ineffective also. Giving up, he fled Chernogorsk as the city got rampaged by zombies overnight, falling to the hordes. Living off the land, he returns, to maybe find his friends or other experts in med, or just to survive as mcuh as he can.
