Radim was born in the city of Glasgow and spent half his life there before his mother died and he was adopted by his new family, The Nivek's and grew up on the streets, doing whatever his older relatives would. Radim was at a loss growing up and never knew what to do to get Big Dick Karel's approval. So Radim would follow his brothers and sisters, doing whatever they did. He stole cars, sold drugs, robberies, whatever he could. However, Radim found his calling running drugs. He loved being on the move and he loved not knowing what would happen next, but since he was so young when he started, Radim would always have a new job to do because of how young he was, meaning less time served if he got caught.
The infection then hit and it took weeks before Radim knew about it because he was high the entire time, but he then spent years travelling Chernarus, meeting his family then leaving them, then meeting his family again, then leaving them, then again and then he stayed... And they headed to Jeleni Ostrov.
