’’’Dragonmarked Houses’’’ are extended families of a single race whose members sometimes manifest dragonmarks. They often have a near-monopoly on certain kinds of businesses and are considered neutral in any affairs between the nations of Khorvaire.

The following Dragonmarked Houses exist:

• House Cannith
• House Deneith
• House Ghallanda
• House Jorasco
• House Kundarak
• House Lyrandar
• House Medani
• House Orien
• House Phiarlan
• House Sivis
• House Tharashk
• House Thuranni
• House Vadalis

There used to be an additional House – House Vol – but it was destroyed twenty-six hundred years ago. In addition, House Tarkanan is a dragonmarked house to which people with aberrant dragonmarks belong, though it is not acknowledged by the other dragonmarked houses.
