Emil was a mere steel worker before the apocalypse, picking up work in his home country of Poland, Chernarus and then Russia, by that respect he was perhaps well travelled, but otherwise lacking ambition and any sense of belonging, what he needed was a change of pace.
Luckily for him, he had little to nothing holding him down, and no severe commitments. And once the apocalypse hit, and the initial shock and awe had passed, Emil found himself in a position of complete freedom and hungry to reap the benefits of this strange new world, politics and previous conflict meant nothing to him. A fresh start was what he wanted, and that is exactly what he got.
Despite what way be alluded, life in Chernarus is not as easy and carefree and expected, and after he found himself there after catching trouble with Russian local authorities, his first goal was to find employment and continue upholding his veneer of lifestyle be it through deception or charisma.
