Discovered Dungeon is again, not a dungeon, in that it's a castle, and not so much discovered (per the first two posts in this series) as it is "interpreted." It's my interpretation of the ground floor of the caslte, based on the actual ruins of Wolvesey Castle near Winchester Cathedral in the UK, and the scale of the drawing should reflect the dimensions of the actual castle (where 1 square = 10'.) I'm planning to finish this out at some point with a parapet level, as well as an in-ground level, and below ground (i.e. "dungeon") level, the latter two of which will be completely invented.
