T-029 Choir

Petr Lask was a surveyor on Anneli Sund's expedition. In year 30, in his second month of training for it, a choir in the ruins nearest the western edge called his name to a survey he was not on. He was at the Institute that night, and he was not told (T-029).

He went through the rift with Sund's six surveyors on Year 32, month 1, day 12 (T-031). When the radio died in the gorge the expedition went on by his bearings (the expedition's field log, a journal find). The last page of his own log is dated to day 52 or 53: the land past the gorge did not turn, the camp was in the old building, Aho and Mo had gone down first and come up quiet, and the voices from the western ruins were calling for him again. "Sund says not to answer," he wrote, and set a line of bearings under it (T-031). The camp's log for day 60 reads: "Lask is gone." (the field log).

The third search found him eight months after the expedition left, standing on a ridge far past the last marked zone, in his own coat, pack and harness (T-031). Lina Dahl called to him and he did not answer the password. It came on with Lask's own walk, the long step and the left shoulder low, and Erik Halden fired first. Inside the coat there was nothing but the skin (T-031). The Institute numbered it as the hollow (T-031).

His bearings pointed deeper than any survey had gone. Tomas Rehn marked them on every map and kept the log on his desk (T-031), and the fourth search followed them until it was turned back (T-032, T-033). Sund's own page, found fifteen years later, begins: "Petr is gone. We go on." (T-054).

Petr Lask is named in 6 case files. The last column says where in each file.
