Isûphiryas (“Great Pit of Years” in Ihrimsû) is the great work chronicling the history of the Nonmen prior to the Breaking of the Gates. In all likelihood it is the most ancient text in existence. Sometime in the fourth century, a copy of the Isûphiryas was given to Cûnwerishau by Nil’giccas, the Nonman King of Ishoriöl, as part of the ancient treaty between their two peoples—the first between Nonmen and Men. During the reign of the God-King Carû-Ongonean, five Ûmeri translations of the Isûphiryas were bequeathed to the Library of Sauglish. Four of these were destroyed in the Apocalypse. The fifth was saved by Seswatha, who delivered it to the scribes of the Three Seas.
