Az, knowing the important of his heritage, made sure he was "fruitful and prosperous" at a point of time in his life. He's uh...Hoping for the best and that he'll meet some of his kids at some point.

To hone his magic abilities Az spent his time high in the mountains with thin air and freezing temperatures. His teacher made him freeze himself solid to embrace and empower the cold. Because of that he feels like he's frozen to other folks, and needs to focus to stay at a room temperature.
