Desert Dungeon

Description
Located at the western edge of the Drylands, the Desert Dungeon is a place with a bloody history. Besides monsters, it is regularly a place of clashes between honest adventurers seeking to uphold virtue and scroundels who don't give a damn on being virtuous. The end result is always lots of bloodshed.

Therefore better avoid it, if possible.

In Ultima VII the Avatar entered the dungeon to loot it, and discovered the latest, bloody battlefield in the process. During that the hero stumbled over a hidden teleporter and discovered the remains of a man called Denyel, who'd been locked-in over a century ago.
