A Vault inside a prison. Perfect for if you want a prison break combined with a heist. Personally I am having the gold in the room be cursed to alert more guards to the area. All of the party's gear is inside the safes, either all in one or separated. I recommend having an NPC open the safe the party tells them to while the party fends off a legion of guards, inmates, or even guardian monsters. It could be empty, filled with junk, or their actual equipment. Maybe have one be a mimic! There are lots of options with this map to play around with. Something to note is how difficult it was to decorate this map. In a prison you won't have chairs lining hallways or potted plants, so It was hard to make the map not feel completely empty.
