From publisher blurb:
All good things must come to an end, even the megadungeon! Edges and Alcoves provides geomorphs with connections on one side, so you can bring your dungeon map to a reasonable and attractive end.
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 tile seamlessly connects to every other tile in the series, providing the megadungeon builder tremendous freedom and flexibility.
This product includes twelve unique map tiles rendered at 100px per five-foot square. The set includes two versions of each tile, one for players and one for GMs. The GM's version shows additional features, tricks, and traps. This set includes (EA1-EA12):
Six 50x50 foot tiles, all with a single entry side.
Six 50x100 foot tiles, all with a single entry side.
A map legend image detailing all map markup.

All maps are ready-to-use PNG-format files compatible with most virtual tabletops. Use them as-is, or combine them into larger maps using your favorite image processing software.
