Below is the whole Tenebris Somnia walkthrough in story order: Ivan's studio first, then Julia's memories, the Aurifer, and the final confrontation. Find the item that opens your next door, solve the apartment and film-school puzzles, and prepare for the bosses along the way. The route overview shows where each chapter takes you and what you need to collect. The chapter guides below provide the room-by-room instructions, with a separate TV puzzle guide for the remote and floor symbols.
Route Overview: Open Seals and Forge the Aurifer
| Part | Where to go | Key items to collect or prepare | Result |
|---|---|---|---|
| Ivan's Apartment | Third-floor apartment B, bedroom, bathroom, and studio | Wrench, developing chemical, empty glass, Aurisatio, green candle | Dissolve the red studio seal and enter the Desiderium. |
| Second Floor | Apartment memories, the window beside Sanguis, and AS Films | Batteries, glove, Triangular stone, AS key, Bathroom key | Activate the studio remote, solve the TV door puzzle, enter AS Films, and burn the rebuilt poster. |
| First Floor | Bar, Door 6 filming location, Door A cultural center, and Ivan's apartment | USB cable and Adapter, Plate with an X, Black Tape, Square Stone, White Candle | Charge Ivan's phone, screen Débora, open the dining-room doors, and reach the White Candle behind the green symbol door. |
| Ground Floor | Floor 0 Film School, its upper rooms, Floor -1, and the building's theater | RCA cable, copper seed and key, black candle, Débora film can two, Cow Skull | Complete Ivan's camera scene, unlock Floor -1, screen the second film, and open the skull door. |
| Agonal Stone | Third-floor bedroom, sealed stairwell entrance, and Vitria's mirror | Agonal stone from the photo-frame drawer; Iron Key and Lapis Fictus Pill from Sanguis | Open the sealed entrance, defeat Vitria, and reach the Film Set leading into Julia's memories. |
| Julia's Desiderium | Altered school, restored classroom memory, and screening room | Yellow RCA cable, recovered belongings, red candle, Lead fly | Purify the apartment key and leave it behind so memories return and the old book becomes readable. |
| Forging the Aurifer | Ivan's red statue, kitchen oven, and Putrefactio mercury pool | Aurisatio, Lapis Fictus knife, completed Aurifer | Free the knife, then treat it with electricity, mercury, and moonlight to forge the golden blade. |
| Final Confrontation | Septimo Arte cinema and the huge-symbol door | Completed Aurifer for the Hermes route; ammunition for Lacuna | Accept Vitria's spell to cross the barrier and face the boss determined by your Relicta Ghost choices. |
The Agonal Stone guide also covers the later Sanguis corridor chase. Complete Julia's Desiderium first, then return to that chase section before forging the Aurifer. Ordinary mannequin barriers can be broken by Sanguis's lunge; red mannequins cannot.
Killing any Relicta Ghost before entering Septimo Arte leads to Hermes and the Bad Ending. Sparing every Relicta Ghost leads to Lacuna and the Good Ending, where you fight without the Aurifer. The fleeing ghost in the Hotel Room already counts toward this choice.
Walkthrough by Chapter
Ivan's Apartment: Entering the Desiderium
Prepare Aurisatio with developing chemical, Julia's blood, and sunlight to dissolve the studio seal. Save at the emerald flame and take the green candle before leaving.
Second Floor: Apartment Memories and AS Films
Power the remote in Ivan's studio, then return to the second-floor television. The Triangular stone opens engraved-symbol doors, while the AS Films entrance needs the AS key retrieved from under its door.
First Floor: Débora Filming and Premiere
Solve the bar's sound puzzle for the USB cable and charge Ivan's phone for projector-room code 5160. The screening reward and Black Tape solve the dining-table puzzle that leads to the Square Stone.
Ground Floor: Film School
Repair the storage-room circuit for the RCA cable and complete the camera-class scenes. Record the television colors in the Old Book before using the black candle to unlock Floor -1.
Agonal Stone: Vitria and the Failed Rescue
Return the premiere photograph to the bedroom frame to obtain the Agonal stone. During Vitria's fight, use the reflected tentacle to create an opening to crack the mirror.
Julia's Desiderium: Recovering Memories
Turn the RCA cable yellow, recover Julia's belongings, and purify the enchanted apartment key. Leaving the key behind restores access to memories, the red candle, and the Lead fly.
Forging the Aurifer
Use blood and burned developed film to prepare Aurisatio and free Ivan's knife. Sunlight finishes that mixture; moonlight is the final treatment for the weapon.
Final Confrontation
Cross the cinema barrier with Vitria's spell. The final guide explains the ending choice and the Hermes fight: destroy the hands, escape the inhale, and finish the weakened boss with the Aurifer.
