Hakotep's flying pyramid has been grounded, but Ezren, Valeros, Merisiel and Harsk must enter the ancient tomb to deactivate the fleet of smaller flying pyramids poised to attack cities across Osirion. Deep inside the Pyramid of the Sky Pharaoh, an untouched tomb from the heights of Ancient Osirion, the heroes face undying guardians woken from ageless sleep, culminating in a final battle with the reborn Sky Pharaoh Hakotep himself.

The dead are walking. The dead are screaming. The dead are killing. Opening the Necropolis of Wati was a mistake. Undead hordes are streaming from the tombs, causing terror in the streets. Zombies. Ghouls. Mummies. Soon the dead will outnumber the living. Valeros, Ezren, Harsk and Merisiel must find the Mask of the Forgotten Pharaoh. But can they trust anyone - including themselves?

Deep in the Osirian desert stands the blank-faced monument known as the Sightless Sphinx. In search of the stolen mummy of Chisisek - the architect of the flying tomb of the Sky Pharaoh Hakotep I - Ezren, Harsk, Merisiel and Valeros track the cult of the Forgotten Pharaoh to its secret headquarters inside the sphinx. There they confront monstrous mercenaries and servants of the demon lord Areshkagal before finally confronting the masked cultists and their leader, the Forgotten Pharaoh.

For almost 2,000 years, the tombs of the Necropolis of Wati have remained sealed - until now. Adventurers from all over Golarion have travelled to the ancient city to find lost treasure and uncover the secrets of the past. But some things are best left buried. As Valeros, Ezren, Harsk and Merisiel face traps, ghosts and undead spirits, sinister forces descend on Wati. The Mask of the Forgotten Pharaoh is about to be discovered - and an ancient evil unleashed. Directed by John Ainsworth.

The Sky Pharaoh Hakotep I has risen and launched an attack against the city of Wati! Valeros, Ezren, Merisiel and Harsk return to Wati to defend it against this menace, only to discover that the attack is just the preface to a larger invasion of Osirion, controlled from Hakotep's own flying tomb. Journeying to the Slave Trenches of Hakotep, the four adventurers must learn how to activate an ancient weapon to pull Hakotep's tomb back to earth.
