Tenebris Somnia Endings: Aurifer Choice and Hidden Routes
The reported main split is whether you kill Relicta after obtaining the Aurifer. Keep a save before that decision; hidden-route prerequisites have community-source limits.

Pick the route before the final approach
Ending and boss spoilers. Gaming Route attributes these conditions to player guides, not a developer-issued solution. Our comparison is a planning aid, not a claimed independent completion.
| Route | Reported action | Check before committing |
|---|---|---|
| Solve et Coagula / #1 | After the Aurifer, spare Relicta and reach Séptimo Arte; Lacuna is the finale | Preserve the save before attacking |
| Magnum Opus / #2 | Kill Relicta after the Aurifer; Hermes is the finale | Sources disagree on the minimum kill count |
| Vivus Ex Mortibus / #3 | After #1 and #2, start again, take the Bible, revisit three puzzles for crosses, then place them outside Séptimo Arte | Check that the prerequisite ending achievements unlocked |
| Renuntiatio / #4 | At the opening of a new game, use the Apartment Key on the building's front exit | Prior-ending requirements are disputed |
Make a branch record
Our recommendation is to keep a small note with the save slot, build, intended route and whether you attacked during the branch. That makes a repeat attempt informative: change one decision while keeping the starting point clear.
Do not overwrite your only branch save simply to test an uncertain hidden condition. The table intentionally does not invent a guaranteed kill threshold, a universal hidden-puzzle code or a developer-confirmed New Game Plus mode. Follow the linked full route for its attributed details and compare it with your own scene prompts.
