I will assume you scrye and then cast the chain of eyes. The bird that you cast it on flies around the lake, around noon and after when it would be crowded.
You see lots of activity around the lake, halflings mostly and a few others fishing and getting water. Its a bit too cool for swimming or water play.
Fishing from the shore, boats, or both?
Can we tell where the visitors to the lake are coming from - e.g., Owt, the troop encampment.
