Umm, what bears? Torkild is a random encounter.
When you find Torkild, he will talk to you, and you will have a conversation with him, he is not with the Werebears, he can be anywhere, close to the coast or in the center of the island.
I found him close to Northshore landing.
He will tell you something about being a powefull beast or something, and you will be like "Torkild, dat yo? ya bro wans ya bac man" he will then say something about not being a humann anymore and he will tranform and attack you.
I just found him randomly dead next to some horkers near a waterfall. Still not sure if he died from the waterfall or the horkers. Probably from the waterfall since horkers are like one of the easiest enemies in the game, I think mudcrabs are more dangerous then these things despite there being a book written about how dangerous they are.
