Testimony
“Four building mistakes, the kind not even the worst site inspector would sign. You don’t have to read anything. Your body recognizes them.”
Anomalies are the mistakes of Level 0. Each one can be recognized without any text, by the way something doesn’t fit. They are places where the building got it wrong and nobody corrected it. There is at most one per nearby zone, and about six per square kilometer overall.

The four
| Anomaly | What you see | Per km² |
|---|---|---|
| Door to nowhere | A frame that leads nowhere | 2.24 |
| Stepping ceiling | 10 cm steps down to a minimum height just over your head | 1.49 |
| Repeated room | The furniture of one room, copied into the next | 1.31 |
| Wrong scale | 2.5 m ceiling and 2.3 m lintels in wide rooms | 0.88 |
How to recognize them
- Wrong scale. A low ceiling or tight lintels in a wide room. Something feels squeezed, as if the space had been built for something else.
- Stepping ceiling. 10 cm steps in the ceiling. Each step brings it closer to your head, and the last one forces you to stoop.
- Repeated room. The same desk in two adjoining rooms, with the same notepad on top. It’s a copy, and the handwriting on the notepad is yours.
- Door to nowhere. A frame at the end of a corridor that opens onto nothing. Behind it there is smooth wall.
How to survive
- Don’t count rooms. Anomalies are made to make you lose count.
- Mark the spot with chalk. Sometimes the mark disappears, and that is a clue too.
- Don’t step through the frame of a door to nowhere. Some people have tried it with a hand and found nothing. See Door as an Object for what you can do with a real door.
The labels on paper maps mark each one with the word “Anomaly,” followed by the type. See Paper Maps to learn how to read them.
What people say
- A floor note (“This door opens onto nothing. I checked with my hand”) goes with the door to nowhere, according to the accounts. See Floor Notes.
- People talk about vertical anomalies, towering ceilings or enormous rooms that open up too early. The archive has not confirmed this.
