From publisher blurb:
Knowledge is the Greatest Treasure!
While some raiders of the ruins of ancient lands lust for gold and glory, the wise seek knowledge and the lore of the fallen empires. Somewhere below the desert sands lies a treasure trove of forgotten secrets and magical mysteries under the wings of the Scribe of the Heavens, Thoth. The cult of this archaic patron of knowledge is long dead, but fragments and clues lead you to a hidden shrine that once bore his name. Will you find legendary wisdom and mystic rewards untold, or will the tests of mind and body within reveal only secrets man was not meant to know?
The Lost Library of Thoth is a 7th-level adventure for Pathfinder Second Edition that brings you the mysteries, dangers, and lost lore of ancient kingdoms of the pharaohs, including a set of brand-new spells like hieroglyphic barrier and the threefold moons of Thoth!
