Calvin Klein was a student at Harvard. He applied to be a foreign exchange student and he picked to go to Chernarus. Turns out he picked a bad time to go so he was there when the outbreak began. He got a bad case of the flu so he went to the hospital thinking it was the infection. He was quarantined and then let out after it being a false alarm. Calvin stayed in his dormitory most of the time as he was seeing in the news that this disease was no good and was turning those infected into monsters. When the other countries attacked he decided to leave and hide in the outskirts as they would probably rally people up and then who knows what. When he left he brought a few things with him like clothes and books. Calvin met a few friends and decided to chill at their camp. The country of Chernarus was left in ruins after the neighboring countries left. John decided to farm a bit on his own and go on runs to the airfield in hopes of finding a plane so he could go back home to his family. He heard news that everywhere the outbreak occurred so he had lost hope of finding his family.
