Found within the ancient Aztec maze on Isla Espiritu Santo, these three black stone tablets are carved with intricate runes. The stone itself appears to be granite, roughly hewn, and extremely ancient. After returning to Bailey Manor with the tablets, the noted occultist, Aleister Crowley, identified the runes as Atlantean. Archie was able to make a conjectural translation of the tablets, though their entire meaning is still unknown. Archie numbered the tablets one through three, though their correct order, if any, if unknown.

Tablet 2 contains an image of the Eye. Tablet 3 has three additional carvings – a heart, a skull, and what appeared to be a penis.
