The Matheson Crime Family is a crime organization and trade consortium which has its headquarters in the city of Matheson in Maar Sul. Its current leader is Lord Vesuvius Matheson. The Family is at odds with the rival merchant city of Jardine and the Nightstalkers, and the rivalry eventually escalated into a brief Matheson takeover of Jardine as well as the Maar Sul Gang War against the Nightstalkers.
