672 Atonement Beacon

672 Atonement Beacon is a minor forerunner monitor, and was present only in the solo RPG "The Apostate", although it is probable he also exists in the 3rd RPG.

Atonement originally oversaw the operations at the gas mine on Hecate, but during the turmoil of the forerunner/flood war, he eventually arrived on Persephone. When the heretics arrived on Persephone, he showed them footage of a scene just prior to the activation of Halo, thus revealing the true identity of the forerunners (although their identity is kept secret from the reader), which compels them to leave the Covenant and become heretics.
