Doom grew up as a noble, living a semi happy life full of lessons and
grand balls. One night at one of these parties, Doom met a man. He
wooed her that very night, and they proceeded to meet with eachother
when the moon rose, because Doom's parents didn't approve of her being
taken with her lover. After a while, her dark angel told her what he was, a
vampire, a blood sucker. Doom was shocked, but not frightened. "Do you
want to spend eternity with me?", he had said in his wonderful voice. "Of
course I do mi Amor!", the foolish Doom had said. And with that, she
was turned. Decades passed and they were happy, until a Human Hunter
came and took her Angel of Night away from her. Doom's hated humans
ever since, roaming the world, killing mercilessly. One night, she found a
new home, and the cheerfull Doom returned, deciding to forget her lover.
