Blackrock Crystal Ball

The Blackrock Crystal Ball is a special crystal ball that appears in Ultima IX.

Description
When the Avatar in Minoc damanded the Blue Codex Lens from Laszlo, the leader of of the gypsies, the man claimed that he's release it to the Avatar in return for getting the Blackrock Crystal Ball. He claimed that the liche Khelereth had stolen it from them, although it is more likely that it had always been in his possession. Laszlo claimed further, that the crystal ball could exactly show the possible future.

After finally finding the crystal ball at the bottom of Covetous after Khelereth's death, Laszlo tried to weasel out of the deal because of a curse that had been put on the gypsies by Blackthorn, but using the crystal ball to see what would happen if he'd do so (it showed their destruction), he relented and accepted his own death to save his people.
