House Tarkanan is a criminal organization structured in mockery of the dragonmarked houses. Its leader, Thora Tavin, is not related to the dragonmarked houses, though she does have an aberrant mark—a fact that she keeps secret from even her closest associates. Thora’s residence, a spacious mansion nestled among the towers of the house enclaves, serves as the secret headquarters of her organization. From here, she personally directs a range of criminal and questionable activities throughout the city, with a particular focus on burglary, assassination, forgery, and loan sharking.
