The Voices of the Spire are a militant sect single-mindedly dedicated to eradicating undead. These pugnacious priests have chapter houses in countries throughout the Inner Sea region, including Nex, Osirion, and Ustalav. Each chapter house is an armory and repository for information on undead. Although they are willing to accept aid, each chapter house is a well-hidden stronghold- a necessity of survivial for a group that regularly orchestrates the destruction of powerful vampires, liches, mummies, and other spient undead. One of their public chapter houses is located in Wati, a city in Osirion nearly overrun by undead in the recent past.
Today, the Voices of the Spire amass in two places. In Ustalav, they launch assaults in The Gravelands, gathering intel on Tar-Baphon and his forces on the Isle of Terror. From Nex, they strike against Geb's undead citizenry, hoping to disrupt one of the largest and dangerous cities of the undead in all of Golarion.
