I am DMing a one-could-say difficult party. The campaign setting itself makes it very difficult as I have decided to provide the characters with a full sandbox experience. They decided to visit Waterdeep and after staying there for a couple of nights, the Rogue of the party decided he wants to rob Waterdeep's treasury.
The way I see it I don't need to design a map of the Treasury as there is no logical way one drow elf could get inside the City of Splendor's vault. On that note though, I tried to find a map of the castle of Waterdeep but I haven't been able to find a good one.
Is there a detailed map of Castle Waterdeep?
