Jonas Berg was a night technician of the sealed level. In year 5 the night staff heard him call from the east corridor for a hand with a door, while he was at his post elsewhere (T-005). A cleaner, Irja Palm, went to look and did not come back (T-005). What had called was the echo, the first threshold that learnt from the staff instead of only hunting them (T-005).
From then on his voice was on a list kept by the night shift supervisor, and a call in it was checked against his post before anyone moved (T-005). Berg asked for the day shift and was refused (T-005). In year 17 he asked to test the quiet room with the echo itself. He called inside the room in his own voice, in the words the echo had used in year 5, and it played nothing back for the full hour. "It has heard me every night for twelve years," he said for the record. "That is the first room it could not hear me in." (T-012).
The replay room showed him to himself, drinking coffee in the old canteen at nineteen (T-015). In year 30, when the choir called the surveyors by name beyond the rift, Tomas Rehn went to Berg for what he had learnt: "When you hear your name, you are already being hunted. Do not answer. Do not go and look." (T-029). In year 46 Rehn still set a new creature beside Jonas Berg's voice when he wrote it up (T-052).
