Publisher's blurb: The Dungeons in Blue series brings classic blue maps to the virtual tabletop! These ready-to-fill maps are packed with rooms, corridors, pits, and caves; all judiciously sprinkled with tricks and traps. Every geomorph seamlessly connects to other tiles in the series, providing the megadungeon builder tremendous freedom and flexibility. Waterways geomorphs depict a variety of caverns and passages connected by underground rivers and lakes. The set has GM and player versions of each geomorph. The GM's version shows additional features, tricks, and traps.
