The Tablets of Ubbo Sathla
The Tablets of Ubbo-Sathla record the occult wisdom of gods who died before the Earth was born. Carved of star-quarried stone, they were guarded in the primal mire by the shapeless, idiotic demiurge Ubbo-Sathla, one of the Outer Gods who inhabited the newly formed Earth.
According to the Book of Eibon, Zon Mezzamalech, a sorcerer of Hyperborea, attempted to read the lore on the Tablets using a curious crystal. He apparently did not succeed, however, and disappeared during one of these attempts.
The present location of the Tablets of Ubbo-Sathla is unknown, nor do any known sources record any appearance of the Tablets after the earliest period of life on Earth.
