Jiri grew up in a small suburb North of Primorsk, he was the son of a mechanic and a stay at home mom with two brothers. At the age of 10 he and his family moved to Zvir in South Zagoria. When the civil war broke out Jiri was the ripe age of 17 about to finish with his schooling he never expected things happening in far off places to effect him. However, on the night of September the 5th 2009 a U.N. supported airstrike supposedly targeting ChDkZ cells in the region missed it's mark and hit on the northern outskirts of the village killing Jiri's family instantly.
Without anyone left for him, he decided to join up with the local Nationalist Cell in Zelenogorsk, and with them gained training in basic marksmenship and survival. Over the next year, he participated in the rightful cleansing of Russian Minorities in the North, and the hunting of ChDkZ cells. With the occasional "Friendly Fire" incident against U.N. troops deployed nearby, although as long as he wasn't caught his superiors never minded.
Following the Civil War, Jiri tried to go back and finish his schooling but he found no desire to. Over time his hatred for the people who led to the killing of his family boiled over, and he began slowly diving deeper into the Nationalist ideologies of the times. When the infection started Jiri saw this as his opportunity, and began doing hit and run strikes on U.N. troops deployed in South Zagoria, in his mind it was just another Foreign invasion of his country with the infect being another ploy. After some time the infection spread, and the situation became much worse than Jiri could've imagined, so Jiri fled into the mountains to the West and stayed there with the remnants of his cell until the time was right.
