Tenebris Somnia puzzle solutions
Three puzzles dominate the searches: the colored floor elevator, the television symbols, and the moonlight purification. All three can change their sequence between saves. Read the Old Book on that file. Do not copy a code from someone else’s video.

| Floor colors | Blue = 3F, green = 2F, red = 1F, white = 0F. Walk the Old Book list from the top. |
|---|---|
| TV | Two separate rooms. Floor 2 uses the remote. The later dark room records colors into the Old Book after you light every set. |
| Moonlight | Silver bottle water from three saves, then the hotel window. A second moonlight step finishes the Viridis knife on the hotel door. |
What the route feels like
The elevator is the one that made me stop writing codes in a notebook. I had a color order from a video, pressed it, and the car did nothing. The Old Book on my own file had a different stack. Once I followed that stack from top to bottom, Floor −1 existed. Same thing happened with the bell jars: the pitches were not the ones in the article I had open.
Floor puzzle
After the dark television room you have a lighter and a black candle. The elevator buttons are colored, not numbered in a way you can trust from memory. Blue is the third floor, green the second, red the first, white the ground. The Old Book lists the order for this run. Enter it from the top of the page downward. When it accepts the sequence, a new stop appears: Floor −1, Iván’s childhood room, and the second film canister.
TV puzzles
The first set is still in the apartment, on Floor 2. You need the remote from Floor 3, which needs the breaker off and two batteries. The symbols on the television tell you which floor buttons open the door on the right. That symbol string is random.
The second set is inside the film school, in a dark room behind a green door. Keep interacting until every television is lit. A Vorax will try to pin you; the achievement He Just Wanted a Hug is the version where you leave the room before it bursts. The Old Book writes the color sequence down for you. You leave with the black candle and the lighter.
Moonlight puzzle
The silver bottle is in the Floor 2 bathroom cabinet. Filling it means drawing water from three save points, and those three points are then gone. The achievement Have You Chosen... Wisely? is this step. Gamer Social Club’s preferred trio is the Floor 2 bedroom, the Floor 3 office, and the Floor 2 director’s office, leaving the film-school save intact.
After Fumus drops the red pentacle stone, open the marked doors and stand at the hotel window in front of Julia’s statue. The bottle takes the moonlight and becomes purified water, which cleanses the cursed film into the third canister.
There is a second moonlight interaction much later. The Viridis knife has to be used on the hotel door “bathed in the light of the moon” as the last of three steps that produce Aurifer. That is a crafting step, not the bottle puzzle, and mixing them up wastes a trip.

Questions people ask
Why did a guide’s color code fail?
Elevator colors, TV symbols, bell pitches, the camera view, Desiderium floor tiles, and the poem photographs are randomized. Use the Old Book on your save.
Does the silver bottle delete save points?
Yes. Drawing water from a save point disables it. Plan which three you spend before you start filling the bottle.
