Altar

"The Altar. If the Covenant fire it up, they'll enable a massive Promethean invasion of Gamma Halo."

- Lieutenant Kwon

The Altar is a structure on Forerunner Halo Installation 03. In 2557, Jul 'Mdama's reformed Covenant faction and his Promethean allies attacked Gamma Halo and retrieved the Conduit. They brought the device to the Altar, where they intended to enable the Conduit to open slipspace portals for Prometheans to invade and give the Covenant control of the installation.
