A criminal group in the underworld of Sharn, founded by Thora Tavin (a.k.a. Thora Tarkanan). In the beginning they were interested in little more than petty robberies and assassinations. As time went on, they became a haven for people with aberrent dragonmarks. Some years ago, a mysterious figure known only as the Son of Khyber has taken over control of the organization. Since then, House Tarkanan has been expanding operations outside of Sharn, but to what nefarious end?
