The great dragonmarked families are the barons of industry and commerce throughout Khorvaire and beyond. Their influence transcends political boundaries, and they remained mostly neutral during the Last War. The heads of each house, not technically citizens of any nation, live in splendor within their enclaves and emporiums located throughout Khorvaire. These dynastic houses of commerce derive their power from the dragonmarks-unique hereditary arcane sigils-that manifest on certain individuals within the family, granting them limited but very useful magical abilities associated with the trade guilds the family controls.
