Ran a session of #TheHallsOfArdenVul at our #osr open table yesterday.

What I exspected: laid back „door dnd“ type of exploration of level 3 of the Arden Vul #Megadungeon

What I ended up with: PCs spontaneously launching a badass retaliation campaign against a much hated gang of halfling extortionists which included backstabbing and hauling a fireball across a subterranean chasm.
