Study is for PCs meeting the quest giver at the start, something that gives that kind of ambience.
The workshop is the main mission space, think Wizards tinkering with stuff and experimenting but it’s now abandoned apart from the monsters that have to be faced down and the main… intelligence of the scenario that is omnipresent.
I can find good soundsets for the fights but not for just ambience inbetween the fights (save for the stone staircase outside which is 400ft up a mountainside).
Any ideas would be much appreciated!
