I have been trying for over a year now to get the Xenophage in every way I know how. For whatever reason, the chest after lighting the beacons that say "emerge from darkness" will not give me the initial quest step for the mission tied to the Pit of Heresy dungeon. I have beaten the Shadow Keep campaign and reunited Eris with her old Fireteam (I own the expansion, in case that wasn't clear), I've done the New Light quests associated with starting a character, Talked to Ikora about helping Eris through her own struggles, completed the Pit of Heresy Dungeon, Did all the Nightmare Hunts, and even replayed the Beyond mission at the end for good measure. Every time I checked that chest and every time that blue glimmer evaporates into absolutely nothing. What am I doing wrong, if anything?
