The map room's door is kept shut and bears a warning plate with its number and a door under a bent arrow. Its partner, whichever door that is, bears no plate. Each morning, when the sealed level is opened for the day shift, a walker on a rope steps in at the plated door and reports which room they came out in; the room is chalked on the board in the anteroom, and its door is kept shut for the day. No one fires at a creature as it goes in at the plated door: the round flies on into the map room, and the creature comes out elsewhere. T-010 is placed in Class I: it does nothing to anyone who stays out of it.

A door that does not lead into its room. It is paired with the door of another sealed room on the level, and the two lead into each other's rooms: a walker who steps in at it comes out just inside the other room, and a walker who leaves that room by its door steps out in front of T-010, and the same the other way round, with a flash and a rush of air at both ends. The pairing changes each time the sealed level is opened after being shut. It takes people, creatures and thrown objects alike. Rounds fired through it do not go with them: they fly on into the map room behind it, which no one has stood in since. T-010 shimmers faintly; its partner looks like any other door.

Rehn's survey of the building (see T-008) reached the south corridor in the autumn of year 14. On the third day of the eleventh month he opened the old map room, stepped in with his chalk and his count, and stood just inside the laundry on the far side of the level, in front of a guard who had seen him come in out of nothing, with a flash. He walked out of the laundry by its door and stood in the south corridor again, in front of the map room. He did it six times before he believed it. The next morning the map room's door led into the stores' office, and the morning after into the laundry again. No one has reached the map room itself: whatever goes in at its door comes out in another room. Only a round, fired through the doorway on Kader's test, went into the map room, and it was heard to strike the far wall.

Rehn's survey book, Year 14, month 11, day 3

Door 14, the old map room, south corridor. Stepped in: stood just inside the laundry, on the far side of the level. Stepped out of the laundry by its own door: stood in the south corridor, in front of door 14, not in the laundry's corridor. Six times, the same. The laundry's guard says I came in with a flash and a draught, as if a window had been opened. The map room itself: not reached.

test log, Dr S. Kader and T. Rehn, Year 14, month 12

Day 1, door 14 led into the stores' office; day 2, into the laundry; day 3, into the empty cell at the end of the stalkers' block, and a guard was posted at that cell from then on. A weighted crate pushed in at door 14 arrived just inside the room of the day. A round fired from the corridor through the open doorway arrived nowhere: it was heard to strike the map room's far wall. Kader's note: the door is not a hole in the building. It is a choice the building makes, and it makes it again each time the level has been shut.

note

T-008, T-009 and T-010 became the first batch of the catalogue's rooms. Director Varga ordered every room on the sealed level measured once a year. The first measurement found a room that was too big (see T-011).

The note you find in the game:

Year 14, month 11, day 3. Found by Tomas Rehn's survey of the building, at the door of the old map room on the sealed level's south corridor: he stepped in with his chalk and his count and stood, with a flash, just inside the laundry on the far side of the level. The next morning the door led into the stores' office, and no one has reached the map room itself.

The door of a sealed room on the lab's lower level that does not lead into its room. Each time the level is entered it pairs with another sealed room's door, and the two lead into each other's rooms.

Step in at it and you come out just inside the other room; leave that room by its door and you step out in front of this one, and the same the other way round. It takes people, creatures, animals and grenades, with a flash and a whoosh at both ends; bullets fly on. Only this door of the pair bears a warning plate, with its code and a door under a bent arrow.

Status: unchanged since the breach; it does nothing to anyone who stays out.

Today it is found at the lab and in the rift.
