AUDIO FILE • CASE 0213
Recorder No. 0213
The recorder was found inside a room absent from every blueprint. Its battery was dead, yet the final recording continued to play.

Incident summary
At 2:13 a.m., cameras in the east corridor failed for seven minutes. When the feed returned, an extra door appeared between rooms 12 and 14. The guard entered; in the next recording, the door was gone.
Available evidence
- The original blueprint contains no Room 13.
- The recorder clock is two minutes ahead of the building cameras.
- The final audio names someone who never officially entered the building.
