Borinall

Borinall is a thief who has stolen the Dawn Ring from the Temple of Lathander during the Baldur's Gate II: Shadows of Amn campaign. He can only be found in his house in the Athkatla's Slums during the side quest, Another Mission for the Temple; otherwise, the house will be empty. 
Borinall will trade the Dawn Ring in return for Gorion's Ward swearing allegiance to Talos. If you're not aiding Talos and lie about it, your party leader will get hit by lightning, inflicting minor damage, which convinces Borinall you're not acting in Talos' name, causing him to turn hostile. If dialog turns to hostilities, Borinall attacks along with three Muggers who come out of hiding to aid him.
