Somnus was born in the Apache National Forest as one of the rare hybrids between a female Mexican she-wolf native to the park and a Timber wolf that was released there by tourists.
The runt of the litter he learned to outsmart his litter mates in order to live comfortable. He would often trick his bigger brothers into fighting each other and ignore him, thus gaining more than his fair share of food or parental attention.
When he became 9 months old he decided to leave his rather small pack, he had no wishes to always be stuck with his idiotic brothers and sisters. He wanted to see the world!
Of course, since he was still rather young he didn't comprehend how dangerous it truly was to live alone. Managing to survive during the first few months by sheer dumb luck alone, he slowly started to build his skills and learned to always try to be two steps ahead of everyone.
Not that it helped him that much... He has a rather twisted luck, somehow managing to step into dangerous, embarrassing or great situations within the same week. He is pretty sure he suffers for such a bad luck because his reactions amuses the spirits of his ancestors.
