Mason Heiral

Mason lives alone in a cabin, deep in the Canadian wilderness.

Spoiler

He was born and raised in a religious cult that originally settled a few kilometers from his current location.

He was well-loved and respected in his community for his hunting skills.

Spoiler

When he was a teenager, he killed his girlfriend, Sandy, and made a knife, using her bone for a handle.
After that, he went back to the cult and hunted down every other member, with a smile on his face. He murdered the entire community, including his family.

In the empty houses of his dead family, he found all the money he would ever need.
To satisfy his new need for a "hunt", he began by hunting hikers and campers who came through his area but eventually, people stopped coming.

After some thought, he decided to visit an auction to 'stock' his mountain with new prey.
