I have little confidence that following them deeper into the lair and where apparently Cyanwrath awaits would be in our best interest but that is just my input. If nothing comes of it otherwise I do intend to have Brannor start combat, given negotiating with the enemy for their interests and demands is not his style and the fact that facing this party plus at least Cyanwrath, plus more dragons I assume, is more than enough to overwhelm the group.
