Night Of The Hunter

Jet Raven is a 21 year old imperial who has no memory of her parents. She was raised by a group of bandits and here she met the Old One. He taught Jet everything he knew of the Dark Brotherhood, Sithis and the Nightmother. He taught her the five tenets and told her that the Dark Brotherhood was her destiny.
But when the Old One disappeared without a trace and the bandits was attacked by guards, Jet ran for her life.
She killed for money while wandering from Cyrodil to Skyrim. Here she heard rumors of a boy trying to contact the Dark Brotherhood and decided to give him a little visit.
