Collaborative Storytelling
The two weird, definitely-not-dragon villagers tell us to take the rescued dragon skull back to the dragon graveyard, its rightful resting place.
'Um, didn't the monsters we just killed say that that's exactly what they were going to do with the skull? We should have just let them take it.'
'That would have derailed the adventure.'
'I think you'll find it would have completed the adventure. We really should ask all our opponents what their plans are from now on, just in case we're all working towards the same goal.'
