Good game, if a bit confusing. I think from now on we should treat delves like full adventures. We'll finish when we finish, we need to stop trying to get it all done in one day.
Tom warned us about undead, so we were mostly prepared. But the lacodons water ghouls were a surprise and we ended up "running". I put that in parentheses because I didn't see it as running as much as trapping the ghouls in the stairwell. Tom said it didn't count towards a milestone and I disagree, but he's the DM and I have to accept it.
