Ravyn Imyan

Ravyn Imyan is a male dunmer theif who joins the Riften  Thieves Guild after four of the main Thieves Guild questline missions have been completed.

Persuing conversation with Ravyn reveals that he is a former member of the Morag Tong, who has since fled Morrowind. As such, he is not on best terms with the Dark Brotherhood, and so turned his skills to the Thieves Guild instead.
