The national animal of Gholsaw is the squirrel for some reason. They're not even native to the region.
I'm thinking maybe there was someone significant in their history who had a squirrel in their heraldry or symbolism. And they got that because they had an ancestor (who lived somewhere else) who survived off of squirrels at one point.
Or at least that can be the legend. Maybe it would be best if no one's entirely sure.
