Long hidden on the shield world of Requiem, the Janus Key is a Forerunner artifact of extraordinary importance. It remained concealed until it was discovered by Spartan teams deployed to counter Covenant excavation sites. According to the Librarian, this artifact was intended to provide real-time locational data to all Forerunner technologies, giving the holder incredible power upon bringing the key to the location referred to as the Absolute Record.
