Exploded Powder Mill

The Exploded Powder Mill is a clear message what happens, if you don't have strict safety procedures with dangerous materials.

Located on the Serpent Isle just north of the Inn of the Sleeping Bull, the Exploding Powder Maker had a factory where very items like Powder kegs and Burst Arrows were produced. However, something must have happened, an accident that caused the explosive products to ignite, resulting in a huge explosion turning the powder mill into a ruin and killing all workers in it. Their spirits were then forced to remain there, not allowed to find peace.

In Ultima VII Part Two, the Avatar found and looted the ruins, in the process destroying the haunting spirits.

Trivia

 * The coordinates are 71°S 52°E.
 * Thanks to a bug, all the ghosts in the building act as if they are the Chaos Hierophant. This can cause an unwinnable situation, if it happens early in the game.
