Calder Voss left the city on the seventh day.
He did not announce it. He was simply present for six days—observing two check-ins, filing notes during three zone runs, eating quietly in the lodging house common room every evening—and then on the seventh morning his room was empty and his name was off the station's observer register.
The only indication that he had left intentionally rather than simply disappeared was a single line added to the second check-in report in Sael's handwriting: Council representative Voss: observation period complete, report filed, departed.
Kai read it at the check-in desk and did not ask what the report contained.
