High Council Chamber

The Council Chamber is an enormous hall within High Charity that the Covenant High Council meets within to discuss policy, discipline/promotions among ranks, and military plans. The walls are lined with large bleacher-like seats. The Prophet and Elite Councilors sit on opposite sides of the chamber. In the center of the chamber is a podium from which an alien may stand to speak or be judged. On one end of the chamber is the entrance to the Sanctum of the Hierarchs, and from this end the three High Prophets sit and address the council. On the other end is an entrance to the city of High Charity.

The council chamber is the first room seen in Halo 2, as well as the first room that the Master Chief comes across in High Charity, after being teleported there by the flood creature Gravemind. He then aims to kill the Prophets and take Installation 05's index to stop the Covenant from activating the ring. However, the Prophets escape through a lift at the end of the hall and the Chief has to kill Brute Honor Guards to advance to the Prophets.

Following the Flood invasion of the station, the Council Chamber was taken over by the Gravemind. Cortana was also in the council chamber in the end of Halo 2. At the end of the credits for Halo 2 there is a cutscene of the Gravemind asking for more answers about the Halos.
