Ultima VIII: The Lost Vale

A vapor-ware product. It was planned that there would be a add-in disk for Ultima VIII, "The Lost Vale". The big doors on the Plateau most likely were planned to be the entrance. Sadly, Electronic Arts, disappointed with the poor sales of Ultima VIII, pulled the plug on the project. Only some screenshots and the box design survived.

As far as it can be reconstructed, the Titans had sealed their enemies, most likely Zealans, in the Lost Vale, together with three of the Gods of Emotion. The Avatar would have the duty to release these three Gods, so that they help him/her on the quest to leave Pagan. Much more, sadly, isn't know about the story. But from the screenshots, some facts can be recovered:
 * The three Gods, who are mentioned in a book at the entrence to the Shrine, are trapped in force fields, and have to be released.
 * Part of the action is high in the mountains, with clouds around.
 * Hydros' legion of own undead appears also.
