Aiden Walsh was born in Reykjavík, Iceland to a Canadian father and a Icelandic mother. Aidens mother would die during childbirth. Aidens father would only remain in Iceland for twelve years then move with Aiden back to Western Canada. In Reykjavik Aiden was learning English alongside Icelandic so the transition to a predominantly English speaking country was not hard although over the years Aiden would lose most of his accent and forget most of his native tongue.
At 24 Aiden would become a park ranger for the natural parks of Western Canada. Traveling around the parks, checking on camp sites and helping spot potential forest fires. Aiden would learn basic firearms safety and knowledge from having to carry a rifle or shotgun in his truck in case of bear attacks and the list of other threats of being alone in the wilds for weeks at a time.
Due to the constant seclusion Aiden became somewhat quiet and not very social. Aiden learned to love the wilderness and prefers to be alone in the forest.
After 4 years of working as a ranger Aiden was ready for a bigger challenge so he moved to the South Zagoria region of Chernarus into the city of Novodmitrovsk. This was due to a job lead, working with a nature conservation and restoration company in Chernarus.
Aiden was only in South Zagoria for a year before the infection struck. Due to his experience and love of the wilderness, Aiden took to the forests hiding from the infected and the chaos.
