History of The Greatest Sacrifice

Overview

The Greatest Sacrifice is a one-step Lost Ghost quest added with Shadowkeep in Season 8, Season of the Undying. Historically (2019), after completing the campaign, Guardians could obtain a Lost Ghost Trace and exchange it with Eris Morn for a Dead Ghost search on the Moon.

Walkthrough

1. After receiving the quest from Eris, travel through the northern part of the Hellmouth into the Gatehouse. Continue down the halls past the black-water room with sword racks. In the next circular room with enemies, check the right-hand grated wall where daylight shines through; the Dead Ghost lies on the ground in front of it. Turn back if you reach the Circle of Bones.

Rewards

The quest record lists no separate item reward. The Lost Ghost searches unlock the associated lore entry and Phantasmal Fragments.
