Pathfinder Adventure Path: Mummy's Mask Part 2 - Empty Graves

Following the opening of its necropolis, the city of Wati is overrun by
hordes of the unquiet dead. The heroes must once more brave the abandoned
streets and dusty tombs of Wati's necropolis in search of the powerful artifact
called the mask of the Forgotten Pharaoh and the necromancer who is using it to
create the undead uprising. But a group of mysterious masked cultists also seeks
the artifact to bring a pharaoh from the ancient past back to life.
Continuing the Mummy's Mask Adventure Path, Empty Graves is a
Pathfinder Roleplaying Game adventure for 4th-level characters featuring
a selection of new monsters, a double-length gazetteer presenting the gods of
Ancient Osirion, and the next installment of the Pathfinder's Journal written by
Amber E. Scott.
