Ceres. Once known as the white queen of the Reef, it is now nothing more than a shadow of its old self. A shadow of days when the Reef did not exist, when humanity ruled the asteroid belt instead of the Awoken. Enxor took that from us. Enxor slaughtered all living things in the belt. But Enxor was felled on Ceres. He died there, before his legions could make way towards Earth.
Now, all of that which was done threatens to be undone. The vile Sect Bones of Enxor have completed their century-long quest. Enxor is rising once more.
One Fireteam however, could make all the difference. Fireteam Argus, the heroes from Europa, have gathered at Ceres, to stop the impending arrival of the Bone Wraith. All the pieces are in place, the race to finish or ruin the puzzle begins now.
