Pathfinder Adventure Path: Mummy's Mask Part 4 - Secrets of the Sphinxx

The heroes track down the cult of the Forgotten Pharaoh to its secret
headquarters inside a giant sphinx statue in the Osirian desert, facing
scorpion-men mercenaries and Areshkagal-worshiping maftets before a final
confrontation with masked cultists and their leader, the Forgotten Pharaoh, who
has been possessed by a fragment of Hakotep I's soul!
Continuing the Mummy's Mask Adventure Path, Secrets of the Sphinx
is a Pathfinder Roleplaying Game adventure for 10th-level characters.
A selection of new monsters, two additional desert locales to expand the
Mummy's Mask campaign, details on the ancient curses of Osirion,
and the next installment of the Pathfinder's Journal written by Amber E.
