Hiero was a human warrior-priest who lived sometime around the year 3000. He was fierce in both hand-to-hand combat and skilled in the use of curate magics. It is said that one morning the gods themselves delivered to him the gift now called Hiero’s Game. Since Hiero’s ascension to serve the gods, the Game has appeared where and when it wishes, to those with great destinies. It cannot be taken by force or stolen; it must be given or found. Often when it has served its purpose it disappears, to reappear at whatever place and time that it may.

Hiero's Game consists of a leather bag containing 40 tiles (of perhaps bone?) and a shallow wooden dish. The possessor of the game enters a brief trance, grabs some tiles from the bag, and places them in the bowl. The resultant tiles give an indication of the future.

The following 30 tiles are known, followed by some of their possible meanings-

1. Arrow - 1) Message. 2) Hit by an arrow.
