Caleb Gallagher, born to Tommy and Aileen Gallagher in Belfast, Northern Ireland. When Caleb was five, him and his family moved to Oldcastle, Ireland... where he grew up. 

Caleb was always into hunting & dirtbiking, he had his first bike when he was eight years old, a 1996 yz80. His father realized that he was really good at it, so he got him into motocross. He carried on doing motocross, winning a lot of tournaments and losing some. He was good enough to make a living off of it when he became an adult and started doing professional motocross tours around Europe with the MXGP. 

After a major tournament in Latvia, Caleb had a request from one of the other riders to go to Chernarus for a minor tournament as some of the locals would love to see a couple professional riders make an appearance... and obviously there was money involved so Caleb couldn't stay away. After coming in second in the tournament Caleb was staying in a hotel with a few of the other guys, that's when the infection broke out and with seemingly no way to leave the country, he was stuck.

A lot of things have happened after the outbreak that shapes the way he thinks & acts, those things you'll have to find out for yourself.
