Desert Dungeon

Located at the western edge of the Drylands, the Desert Dungeon is a place with a bloody history.

Description
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 it is better avoid it, whenever 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 in one of the caves and discovered the remains of an unfortunate man called Denyel, who'd been locked inside a cave without exit over a century ago.
