The Supreme Council

The government of Marentia. The Council has nine members including the autarch who chairs all meetings. Originally, in 282, the council had seven members and was the highest level of authority. When Marentia was reformed in 441, the primary role of the council was then to elect an autarch from among themselves. And when Celestian I introduced the eight magical colleges, he raised the number of seats in the council to nine, so that each dean could sit in the council along with the autarch. When the college of illusions was discountinued, the council had eight members for a time. But after the college of necromancy had followed suit, Ashanar I introduced the titles Lord Protector (a kind of war minister) and Enforcement Counsel (who is in charge of the wizard agents). 
Currently the Supreme Council numbers Autarch Nimrod IV, Judas "Gornard" (Diabolical Counsel, that is dean of the college of summonings), Karlian "Ashanar" (Defense Counsel, that is dean of the college of abjurations), Alterations Counsel  Xyon "Politorn", Enchantments Counsel Hamilkar "Nistris", Divination Counsel Mirton "Iktemar", Evocation Counsel Tolvang "Eulan", Enforcement Counsel Silvestre "Celestian", and Lord Protector Ekilmer.
Update: Nimrod IV is died 1119, Eulan (I) is now autarch.
