Sometime in the ancient past, the Oracle (unofficial) made a prophecy that a hero would come to defeat a Minotaur that had taken over the Catacombs of the Ancients. The Cliffs of Logic were created to test individuals to find the person with a keen mind and body who could defeat the Minotaur. The Winged Ones devised a series of tests, these included the stones of stealth, and the related riddle; The grand staircase meanders up the face of the cliff.
