Telling the residents of the first valley about the dam will have to wait for at least a little; showing up before dawn isn't likely to win you any friends, at least not in Cain's opinion. He does take a slow flight over the valley, though, checking if anyone's awake, but the place looks deserted. The lights that were on earlier are all out now, and nobody is outside yet.
The river's flow is a little down from where it was yesterday, no longer threatening to breach the banks, instead safely within their confines, but still moving quickly and most of the way up the riverbanks. The administrator is up already when they return to the Inn, and Cain can see him working in the office.
"Administrator Damien, I managed to complete the tasks you set me last night. The dam was placed one valley further away since the one closest to us is occupied," Cain explains, and the man looks shocked.
