Sasquatches

Sasquatches are a race of giant humanoids.

Overview
Sasquatches are a race of giants that inhabit the northern mountains. They were misshapen humanoids covered in white fur, but actually it was said that their ancestors were giants, but have since been much reduced since then, becoming something like overlarge apes.

In the past the sasquatches were just one of the dangers faced by the harefolk tribe in the mountains. The giants occasionally picked off villagers. That however ended around a hundred years ago when the sasquatches began to get organized under the Ice Witch and began to systematically hunt down the harefolk every single day in honor of the era of winter.
