House Tarkanan is a criminal organization based in Sharn consisting mostly of bearers of aberrant dragonmarks.

House Tarkanan has a reputation for assassination, thievery and other unlawful deeds.
Organization
House Tarkanan is not itself a dragonmarked house, but instead names itself in mockery of the dragonmarked houses that slaughtered their aberrant predecessors in the War of the Mark.
House Tarkanan offers services in assassination and thievery. It also recruits those who have aberrant dragonmarks and teaches them to use their marks as well as how to fight or steal.
Many members of House Tarkanan have adopted Tarkanan as a surname to indicate their allegiance to the house. Senior assassins are known as barons, while more junior members of the house are called lords and ladies.
