From publisher blurb:
For well over a thousand years this impenetrable and mysterious stronghold, set deep in the heart of the Plane of the Dead, has remained a silent observer to the events transpiring upon the surface of Netherworld, a fortress meant to house the deepest and darkest secrets of arcane necromancy until the end of time. Unknown to even the most experienced of magic-users, the Black Fortress is also the last location of the Black Skull Staff, an artifact of arcane sorcery rumored strong enough to destroy the deadliest threat to Netherworld's continued existence, the Greater Demon Holofax. Equally as dangerous is the staff's last known owner, an enigmatic wizard known only as the Death Master.
Intended for a party of 4 to 6 brave adventurers of 8th level to 10th level Dungeons and Dragon's characters, this module was designed under the Open Gaming LicenseTM and the D20 System TM created by Wizards of the Coast.
