Would you or wouldn't you have a dungeon?
I would definitely have one
Would it be hidden?
Yes
Describe in great detail what your dungeon would be like and what would be in it.
First I'd pay off everything I owed, then buy a better house. Then I'd make the dungeon. Would be hidden behind like a bookcase or something (just for giggles lol). There would be all sorts of torture mechanisms and what not. Perfect for any slave that enters
