Nightmare Keep (Advanced Dungeons & Dragons: Forgotten Realms Adventure FA2)

A would-be conqueror is raising hordes of undead insects beneath Wolover's 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.
