Fate wanted Yak-Tar to join Berzogs Sqaud. So he stood down and waited somewhere in the wilderness until the squad passed by and he joined after surviving a strike by Friedrich, which was a test of his strength. He didn't know what fate planned for him until he was crushed be the giant hammer of a daughter of Talos in Neverwinter on Fearun. After that he was resurrected by Tyr who show him a new way in life. The way of justice. So Yak-Tar realized that "what will happen will happen" is only one side of the coin, but "what is just SHOULD happen" is the other. Since then hes trying to learn what real justice is and also to advice Berzog to leading the troop according to what is just.
