The Faceless Ones-An Eberron Campaign
Council of Twelve
The Council of Twelve operates out of a 13-tiered keep that floats over the city of Korth, in Karrnath. The council oversees the Twelve, an institute of learning that lives in the keep and is devoted to studying the dragonmarks, their magical and practical applications, and their potential for profit.
The Council is supposed to be made up of one member from each House. However, with House Thuranni recently split from House Phiarlan, and House Cannith sending 3 members, one for each branch of the House (Sharn, Aundair, Korth), there are currently 15 Council members.
