Mariah was born in Richmond to Hypnos and a phsychologist, Kathy Dooley. Ever since she can remeber she was tired no matter how much she slept. When she turned 14 she was sent to Camp Half-Blood after a couple of Harpies attacked her.
Mariah always slept during class so she didn't make a lot of friends but enough to keep her happy. When she turned 10 her mom tried to put her on a medicine that would keep her awake which didn't work at all. The only thing that kept her awake was talking. Her fatal flaw is holding grudges against people who rudely wakes her up or betrays her trust.
Mariah looks slightly older than she is with blonde hair and bright blue eyes. She wears baggy clothing so she can make a pillow or blanket whenever she wants to sleep.
