Dark, Hazel is not the oldest, she was just born before anyone else. She is infact 13 as her years in the underworld don't count as she didn't age. Wait a secound, I just had a thought, do you people think that she is 13 because 13 is an unlucky number associated with death and Hades's cabin is nimber 13?
