The Forerunner Email was sent to all recipients of the Xbox Flash newsletter and seems tied to AdjutantReflex. It consists of a cryptic poem alongside an image depicting a Forerunner wall with a symbol on it, the same symbol used as an avatar by AdjutantReflex and the same observed by N'chala as Forerunner machines built the object speculated to be the Ark.
