OK, that one sentence from the shady bishop. Maybe the wywern was the big fish here and not that it's gone there's going to be another, bigger fish? Or a bit smaller, but still quite big fish, a school of them? Like, the wywern was a protection against greater danger?
Or maybe not, maybe he's just deceived by his beliefs? I really hate these cliffhangers. Every damn chapter. argh. give us a break.
