The Tastan civilization succumbed to extinction many years ago; their only legacy being the mysterious Tastan Caverns. Some believe the caverns hold an invaluable treasure, while others say great wealth is attained through the knowledge and technology left behind by this advanced race. Take on the role of Beni and search for the truth as you enter the Caverns on a dangerous quest for riches. As you begin your strange and perilous journey, a female sentinel, a holographic image with advanced A.I., positioned there by the ancient Tastans to guard their sacred caverns, awakens. She appears throughout your quest with a sometimes benign purpose, but other times with calculated intentions. You will soon realize that behind the mask of illusions, the sentinel is much more than she appears to be - her dark purpose will threaten your very existence.
