From the Ward Grimoire
Carved into the alagai hora (Demon bones) by dama'ting, a Prophecy Ward reads the currents of magic to make predictions about the future. Their magic pulls the demon bone out of their natural trajectories to answer questions spoken in prayer to Everam. The processes used both to make the dice and to read them are closely guarded secrets of the Krasian priestesses. It is death to share them with outsiders.
