Born in Canada, Stevenson’s family was fairly poor and in a small cabin built by his father. His mother was terminally ill and his father, a carpenter, was always at work. Growing up he was pretty alone and home schooled. When he was just 7 his mother passed and his father packed up and moved them to Minnesota, USA. Stevenson acclimated well to his surroundings, making friends fast with the neighbors. His father became a drunk to cope with the loss of his wife but got a job at a factory.

When Stevenson turned 18 he joined the US Army. He was sent to Afghanistan and during one of his patrols his unit was ambushed by a terrorist cell. They would get out fine but after they got back to base and was asked to come talk to command. When he got there a man asked him to sit down at a table and introduced himself as FBI Senior Agent Williams. Agent Williams would interrogate Stevenson about what took place eventually telling him that what he saw is now classified and is to never talk about it again.

Stevenson eventually got moved to a new unit of rangers led by a man named Johnathan Miller. Stevenson looked up to Miller, respected him. After a few years Miller left to run a group called PLIKT, which ended up being filled with snakes. After Miller left PLIKT he called Stevenson into Nyheim and Stevenson answered the call to help Miller out.
