The supreme leader of the Clans, elected from the members of the Grand Council. He or she also serves as the arbiter between Clans in times of crisis, acting with the power of the Grand Council. The ilKhan enjoys wide ranging powers in military matters, but his or her power is not absolute; the ilKhan answers to the Grand Council and his authority is limited to those matters ordinarily belonging to the Grand Council. The ilKhan normally may not interfere in events deemed internal to a Clan, but when the Martial Code is in effect they operate largely unhindered.
