Dungeon Craft Castles & Keeps by 1985 Games is a modular terrain set for D&D and other tabletop RPGs, built around castle walls, gates, towers, corridors, and hidden rooms you can rearrange for new maps every session. It includes 1000+ double sided tiles that work with dry erase and wet erase markers, so you can sketch routes, traps, and encounters right on the map. Add lively details with a big mix of pieces, from defenders and townsfolk to invading forces, plus siege themed elements like catapults and bulky brutes. Great for building battle maps fast, then remixing them for the next adventure.
