Like I said, Vorris is Hagers-bound or bust. He won't participate with the demons unless either they force him to, or Nahargu'ul tells him to sidetrack a bit. You or dragonmancer playing the scouts, running into Vorris along the way out of Talpike, having a tussle, would be at least my preferred way of handling things if the intention is for [i]all[/i] of the scouting parties to be dealt with.

I can handle that all myself, but it's more fun to do a collab, honestly. Your call.
