“In 4651 ar, a Chelish scholar named Imivus became fascinated by the history of Ancient Osirion, a fascination that swiftly grew to an obsession after Osirion’s government denied him permission to mount an expedition into the desert sands. Frustrated and with wounded pride, Imivus organized several secret, illegal expeditions, but he vanished in 4657 ar during his 11th such journey—an expedition that sought the Veinstone Pyramid of the Four Pharaohs of Ascension. Imivus hoped that discovering the rumored pyramid would establish a firm connection between Ancient Osirion and influence from an alien presence from the Dark Tapestry beyond the stars. In particular, Imivus was chasing the legend of a long-lost book called The Last Theorem—a book that he believed would answer all of his questions.”
