The Far Tower was a Covenant tower on the orbital city High Charity. It featured some Holo-Pedestals, a Gravity Lift, and three landing pads for Phantoms. This is where the Prophet of Truth boarded a Phantom to reach the Forerunner Ship and where the Prophet of Mercy was murdered by a Flood Infection Form.

It was connected to the Mausoleum of the Arbiter by a solitary bridge.
