In the heart of the Inner Sea region stretches one of the oldest human empires still standing today: the mighty and mysterious land of pharaohs and pyramids known as Osirion. Hosting as many accursed tombs and treasure-filled ruins beneath its shifting sands as above, Osirion offers no shortage of adventure for characters of all sorts. From the cosmopolitan capital city of Sothis, seat of the Ruby Prince, to the desolate wastelands of the Osirian Desert, discover the might and majesty that lifted humanity out of the Age of Darkness and could potentially usher in a new golden age if unearthed from the past.
Learn about every corner of Osirion, the backdrop of the exciting Mummy's Mask Adventure Path, with this comprehensive sourcebook on the nation, its history, and its inhabitants. Within these pages you’ll find:
