Mason Blackwood is an ex-military US soldier expelled for disobedience. After being expelled, his cousin invited him to come to the Czech Republic to work for him in a "Free Trading Company", where he would act as a bodyguard/security officer. When he got there, he discovered that his cousin was lying and was working as a smuggler to do illegal transport of guns and drugs for all Eastern Europe. Mason then thought on turning his cousin to the police, but the amount of money that he was making smuggling was satisfying enough to make him keep working in the area. When things started to get messy in Chernarus, his cousin started shipping weaponry to the Chernarussian Militias, and often would send Mason as a negotiator. In one of these negotiations, the Outbreak happened, leaving Mason trapped in Chernarus. The Chernarussian Militias tried to get rid of Mason, but he managed to get out alive after disappearing near Green Mountain. Nowadays he roams Chernarus looking for a way to survive and, if luckily, manage to get out of this God forsaken land.
