As Beni, players enter the Caverns on a dangerous quest for riches. Along his strange journey, he encounters a sentinel charged with guarding the tombs. This sentinel, a holograph programmed with advanced A.I., awakens only when the tombs are disturbed. She appears to Beni throughout his quest, sometimes with a benign purpose, but other times with calculated intentions. Beni will soon realize that the sentinel is much more than she appears to be. Her dark purpose threatens his very existence.
