Happy Birthday! Not.

Callidora is an omega, the lowest rank in the Alpha heir line. She was born with long term temporary blindness, so she had to have help with everything. She was the youngest in the family of 6 kids and was treated as though she was the next in line to be Alpha making her siblings extremely jealous. When her parents weren't home they would pick with her by moving things around, and hitting her. One fateful day, she could see again. She hated the world through her eyes. It was depressing and painful to her. Soon, her parents mysteriously die, and it's somehow blamed on her. Her older siblings made her life a living hell. She spends her life as a slave to her older siblings. One day she can't take it, so she takes action.
