The Fire Knives were a band of assassins that operated out of the city of Westgate, under the approval of the thieves guild known as the Night Masks. The group was led by Lord Tagreth Cormaeril, also referred to as the Grandfather of Assassins. Agents of the guild operated within all the major cities in Cormyr, as well as Chessenta, the Dalelands and Sembia. They were particularly dangerous because of their ability to blend in with high society along with their eagerness to accept almost any job, if only to hone their skills.
