Welcome to entry 21 in my A-to-Z blogging challenge,
wherein I attempt to do 26 d30 charts during the month of April.

Essentially, this page generates dungeon entrances. I know it's a bit of a stretch to make it a "U" entry, but I think it works... it's entrances that go from above ground to below ground (and are, therefore, underground entrances).
