Supreme Councillor

If the USR’s High Council is equivalent to the Covenant’s Council of Heirarchs, then the Supreme Councillor is the USR’s High Prophet.
The Supreme Councillor rules over the rest of the High Council, keeping order and capable of overruling laws deemed unnecessary (only in the case that such an action is justifiable). He also has complete control of the United Sangheili Republic Armed Forces, though this is usually taken care of by the Imperator instead.
The Supreme Councillor is elected only after having been a High Councillor for five years.
