From the Back of the Book:
Nightfang Spire has long brooded in lonely silence, shadowed within the walls of a steep defile. A tall stone column, it resembles nothing so much as an enormous fang of some vanished, mythical beast. Once, a fervent relgious order thrived here - before its god was slain. Embacing that death, Nightfang Spire was transformed into a massive, hollow mortuary filled with the restless dead.
Heart of Nightfang Spire is a stand-alone adventure for the DUNGEONS & DRAGONS game. This adventure challenges 10th-level heroes who follow the rumor of a dragon's hoard to the imposing edifice known as Nightfang Spire. When they arrive, the truth about the place is revealed in all its awful clarity.
