Delving in the Dark

From the publisher:
There are a lot of great, simple dungeon generators out there, but I couldn't find one that suited my current needs, so I decided to make one.

In one page you'll find system-neutral tools to create, either in advance or as you play, a dungeon including door status, room contents, traps, encounters, oddities, and dungeon dressing.

Included is a zipped file containing the possible dungeon areas, from halls to rooms, both with white background and transparent. I have tested these out on Owlbear Rodeo and I think they work a treat.
