Chance has always been a person of solitude, driven through the belief of not to trust the world. He see's the world full of greed, nothing but hurt and pain. Despite being within solitude with these thoughts, it only pushes him to wake up everyday. He see's himself and this belief in a reflection, like looking in a mirror, instead of himself. He see's the very belief he endures.
This belief was always pulled along with him throughout his entire life, coming out of what was once an abusive family upon moving. Practically left by him Day 1 to rot with the other dead wanderers that now rule this world.
He didn't seem to actually originate in Chenarus at the beginning of the outbreak, infact. Some of his gear clears the suspicion of absolutely different origin.
The sudden move of country in a world full of even more greed than before wasn't impossible until he managed to find himself in the foreign continent. He keeps the very patches he ripped off the uniform he wears, if he were to share. They would be patches of the American flag.
Chances life before the outbreak were pure routine of work, eat, sleep and repeat. However, he was one of a few sorts of people that prepped for such a deadly end of the world/government scenario. From Day 1 of where he was and of the for sure fact everything was going to shit. He remained careful and in a bunker he stocked up with food and had coverered up with bushes and all sorts of natural obstructions. He stayed in this bunker for a couple months, noting the loss of anything outside, any and all transmission coming from his radio eventually went silent. Cable stopped, internet was already dead before all of this and he relied on his Power generator and his surplus of fuel. Eventually he had unlocked his little bunkers vault like hatch to find himself in an entirely different world, more run-down and scarce of resources and food. From this day forward, he'd try his best avoiding large cities and open roads. He lived near the coast of an unmentioned state, eventually using the remainder of his fuel and then some to cross to Chenarus. His thoughts were that he might find his distant relatives, family members that had moved near ages ago.. however he wasn't even sure where they lived within the continent, or if it were even safe. He barely looked into the tv through fear of what he might see or hear. He only kept it on incase nuclear strikes would be nigh. He was unsure of what he was truly walking into, was it another world of more or less dead walking around.. or was he going to find a law filled country still standing. It was a mystery to him and he continued.
Eventually he found himself at the coast of Chenarus, stepping out to only find himself a new home in another dead ridden country. Leaving his boat abandoned on Day 632.
