Disks of Mishakal
The Disks of Mishakal contain the teachings of the gods of good, such as marriage rites. They also teach about the gods of evil and neutrality, since balance is needed throughout the world. They are thin, lightweight, and made of platinum. After the Cataclysm, the disks were hidden in the ruined city Xak Tsaroth. They were guarded by the black dragon, Khisanth (Onyx). The Disks were found by the companions in the first book in the Chronicles series called Dragons of Autumn Twilight.
