Councillor
From Halopedia, the Halo wiki
Elite Councillors are the highest ranked Elites. They share power with the Prophet Hierarchs and the Prophet Councillors. They make the political and army decisions of the Covenant. During the Civil War of the Covenant they were stripped of their rank (it is unknown if there are now Brute Councillors).
Appearance
The Councillors wear large, distinct and oddly shaped crowns as ceremonial helmets. These helmets are light blue in colour. For armour they wear white plates like Ultras.
These Elites appear only five times in Halo 2.
- In the end of the level Gravemind, next to the mausoleam of the Arbiter room, carrying an Energy Sword.
- In High Charity's Step of Silence, while the judgement of the future Arbiter takes place.
- In High Charity when the Elite is carrying a Plasma Sword in the Mausoleum of the Arbiter fighting the Master Chief.
- In the Arbiter's battle against Tartarus.
- In The Great Journey when you free 2 of them and some Hunters.
