Mark Vern was born and raised in the United States. Once out of high school he began working as a private detective because it seemed interesting to him. After the years, he started his own small business that handled local detective work that the police were not interested in. This business never really took off, but it always did make a steady profit. Recently though, Mark was decided that he wanted to maybe sell his business and travel. However, he has since taken an interest in the recently quarantined zone of Chenarus, and plans to attempt to sneak into the region.
