Bound in Sorrow
Complete tiers of the Nightmare Containment public event within the Derelict Leviathan and bind your Vestiges of Dread at the Nightmare Harvester after completing the final tier to create a Bound Presence.
Each additional time you bind after completing the final tier has a chance to reward a Bound Presence.
Eris recommends that you return to the Leviathan to confront powerful Nightmares in the Castellum. Defeat the Nightmares and contain them in the Crown of Sorrow, paving the way to begin the next ritual of severance.
