Probably sheets and layers for each level.

The peninsula between Naples and Salerno, Italy, South side, has a number of small towns like that. No idea what it looks like now as I was last there about 1972.

Update for 3a -03. I think this is it for this map.

3a_03 text

20 ) 3 pits, some wood debris, and a banquet table. food has spoiled.

20 B ) a defensive area, that didn't work. Appears that diners at this banquet were surprised, but were able to defend themselves for a while.

21 ) a sandy floor and a marine dungeon. Water ripples around a wall out in the water. That should give a clue there is a shark out there. Some small fishes must keep it fed. But how vdoes it continue to live ? No, not a were-shark.

A small boat is there, but no oars, to take you out onto the water. There could be treasure, but it isn't visible from the shore. Watch out for the sea urchins if you hgo wading out into the water. And don't pet the shark !

22 ) a circle room. Debris blocks a smooth walk around the water. Can the shark in room 21 get over here ? A secret door leads to mold floored passageways and rooms.

23 ) A one time swimming pool. Appears to get 5' deep, just under 2 meters.

But is it safe ?

24 ) in front of some castle walls with towers. Doors lead away from, into, this room.

24 B ) 3 giant ants, a scouting party looking for food. A ruined rock building. Two small skeletons in the building.

A skeleton behind a row of amphorae... not very good for defense. Doesn't look like they have been opened.

No entrances to the three towers. If ladders were used to get to the top of the wall, they are gone.

passageway leading to room 25. A skeleton under ceiling debris. The ceiling is smooth.

25 ) two broken tables. a pile of wood debris with a spike pole with hair, and a spike pole with a human skull on it. Three spike poles with hair on them, on the floor.

26 ) bat guano, 4 blue mushroom areas. One is glowing, probably shouldn't touch that. Wood pile.

27 ) three blue mushrooms, one is glowing. Bat guano, 4 areas of white mushrooms... deadly nightshade ?

Three amphorae, 2 chests. Probably have treasure.

28 ) Two tables with chairs. Three comfy chairs. Why aren't they damaged ?

29 ) Two tables, the chairs are to big to fit into the U-shaped area.

30 ) Looks like a lecture room. One comfy chair, 6 blue less-comfortable chairs.

The passageways become gray floors instead of sandy floors, or moldy, like the rest of this map.

Hard for me to see if it is darker.

An update. I added water ripples to the wall in the water. Not all example maps that had the Water ripples sheet on it, had the effects.

20/20B is an old banquet hall turned into a defense room.

21 fish and swimming. Someone brought in a bull shark and ruined it. Or is it an ilusionary shark ?

22 a sort of standard circle room, with a few skeletons and lots of wood debris. And maybe a treasure trunk.

23 a 5' deep swimming pool... or is it ?

24/24 B a defensive work... too many paths to get behind the wall.

25 thru 27. Moss, algae, or green paint/tiles ? Working on ideas for them.

Not sure if waves along the shore would work or not.

It kept switching between DD3 Color and Marine Dungeon. i decided to make MD01, and insert it into the Dungeon map. Worked, and much faster.

I was going to do a long prequel of text, but I decided to just go ahead and post the jpg
