Twilight Black Swan

I am selfish and steal other people's lives to live; I am cold-blooded, and I am used to repaying kindness and revenge. The elf continent is sleeping because of me, and the elf mother tree is withering because of me. The most kind and gentle elves curse me, and the elf mother tree does not recognize me.I'm Eliza the half-elf, and I don't believe in villains who are good or bad.I really should die according to their wishes.But I—I still want to live.
