I'm Lalya Ulric a wereangel. I can turn into a wolf with the help of Alusia the wolf inside me, but when I turn back I'm an angel. I ran away from the pack when I was 19. I was trying to battle The Darkness. The Darkness was a simple man. You don't say his name though, Legend has it if you say his name he will come, he will find you, and he will kill you and devour your soul.
