Kyran knew Gael did not suggest investigating Howling Pass, believing Cyneah might be there. Since it was more or less established that she was at the place where the old man asked him to go— unless the latter wanted him to go to 'Howling Pass'— there was no need to look for her there.
Thus, Kyran knew Gael suggested that place while thinking of the missing people in the Human plane.
'Do you recognize any of them?' Kyran asked, suddenly realizing a problem.
If those 'complete beings' were really from the Human plane and ended up here after accidentally entering a rift, could Gael have 'eaten' some of the Conclave's people?
Kyran felt an incoming headache at this possibility.
Gael shook his head, 'No one. If you want to ask if there were anyone from the Conclave or Mannick's people, I don't think so. These people are pretty old compared to them.'
