So clearly I did something out of order, but I don't know what. Maybe going back into the mountain pass a second time, after the Karlach trick, forces completion anyway? I did buy the periapt, but that was it. I thought you could keep going back and forth, at least for a while.
Is there a place to verify their deaths on the road? Like I said, the only evidence I can see in the grove was an unusual blood stain, and one person commenting on what a shame something had happened. Logically, they must have died on the road, but why does it seem like the druids killed them in spite of quest status?
At which point in your timeline did you enter the mountain pass for the first time? Sorry if you already wrote that and I missed it somehow. You get a big warning window when you do that tells you that you will change the state of the world.
Some tieflings you can find dead, Arka for example if you allowed her to kill Sazza, and supposedly Rolan if you told him to leave the Grove, but I have never found him.
