Hrmmm.

Orchid will obviously go as the challenger.

But we can't bring too many people or else the dragonborn dood is going to think something's funny going to happen.

I'd say I bring Parum to escort the family back to the keep and tell the dragonborn "release the prisoners first".

Then either Torus or Kyra, ideally Torus, to come and heal Orchid if he falls. While I plan to kill this dragonborn, unless we've gotten a full rest I'm without rages or a reckless endurance. I got an idea how to deal with this guy, but I need to win initiative for it to work.
