Far Tower
From Halopedia, the Halo wiki
The Far Tower was a Covenant tower on the orbital city High Charity. It featured 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.
