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. That said, many whisper that the barons and leadership of the various Houses rival- or even eclipse- the power of any king, queen, or noble, and some scholars have even suggested their inter-national scope may be a glimpse of the future of governance and power.

In Throneport, 10 of the 12 Dragonmarked Houses are constrained by the Treaty of Thronehold to only own land in Trades Ward. Deneith and Vadalis are both limited to their extensive, pre-existing complexes within Thronehold‘s walls. Regardless of these official limitations, every House seeks to test these boundaries and is home to many clever and knowledgeable solicitors and barristers and has many friends within Throneport’s government.

Their collective “self-governing” body is known as The Twelve.
