High Charity

In the video game Halo 2, High Charity is the name of the mobile capital city of the Covenant. It is a large bulb-shaped structure, actually a massive starship capable of slipstream jumps like any other vessel. The city houses the majority of structures sacred to the Covenant, such as the chamber of the Council, the Mausoleum of the Arbiters, and the sanctum of the Prophets. The power source is in fact a Forerunner ship, rigged up to siphon off the engine power and send energy to the city.

During the course of the game, Flood infest the city and the Forerunner power ship takes off. The city is abandoned and assimilated by the Flood, drifting in the middle of a space battle. Whether it will be reinhabited or destroyed in the future is unknown.
