Major story spoilers follow. Open a topic only when you are ready to read the revelations.
Four confirmed ending routes
The official achievement list numbers four endings. Use the complete ending guide for trigger conditions; keep this page for the story and character interpretation.
What is the Desiderium?
The old book describes a temporary space created by the ritual. Its rooms draw on the ritual participant’s memories. The red replicas are Rubralacras, while the Relicta are separated fragments of a person’s soul. They are related phenomena, not interchangeable names for every monster.
What does the key hide?
The recovered phone conversation reveals a spell copied from Iván’s key onto Julia’s. It draws her into the plan and obscures memories. The later scenes reframe the relationship and the making of DEVORA; earlier statements should be read as partial accounts, not neutral explanations.
The ending-route distinction
The theater corridor has separate conversations for a route where Julia has killed mercurial Relicta with the Aurifer and one where she has not. If you want to preserve the non-killing branch, keep a save before completing the weapon and avoid using it on these beings. Earlier required fights against physical creatures are not the same decision. The exact kill threshold and every final variation are not established here.
Hermes, Lacuna and the final conflict
Hermes is the name adopted by Iván’s Relicta; Lacuna is Julia’s separated part. The final dialogue concerns control, ownership and Julia’s attempt to reclaim her life. The less vengeful dialogue is a meaningful branch, but the confirmed dialogue branches do not establish an official hierarchy of endings.
