Ulf was once called the Obsessive because his passion for magic and alchemy was way beyond that of any other werewolf in his clan. Although he didn't get much support from them, he managed to do a lot of research with very few resources.

Even Vasilov praised him; Ulf has always been a hands-on kind of guy, and his decisiveness is something many people lack. It's also why he could gather so much information and share it back with the clan.
