Nightmare Keep (FA2)
A would-be conqueror is raising hordes of undead insects beneath Wolovers Keep in the Veilstone Peaks. This evil being was once a lich¸ a powerful undead wizard... but that was not enough. Now something strange exists beneath the Keep¸ something repellent - and strong beyond measure.
Nightmare Keep: for the AD&D game adventurer with courage¸ a strong stomach¸ and superior firepower. This adventure is set near northwestern Cormyr in the Forgotten Realms¸ but it fits easily into any ongoing high-level campaign.
