The Thaumaturgs, or Theurgists, were the organisation of mages that made up the ruling class and bureaucrats of the Kingdom of the Thaumaturgs, in north-western Jacuruku. The Thaumaturgs were ruled by the Circle of Nine, or Circle of Masters, which comprised of the nine most preeminant mages in the nation, the Nine Masters with the head of the Circle of Masters being the Prime master, Surin. The Thaumaturg nation was far more developed than the surrounding kingdoms, with more complex mechanisms for such activities as milling, with the lower class effectively being serfs.
