Lost Eyrie of the Demon King
An otherworldly evil festers in the bowels of the Lost Eyrie of the Demon King. And now that evil has attracted a powerful servant—a servant wreaking death and destruction on the surrounding countryside and villages. The local villagers need adventurers to eradicate this terrible threat, but will the heroes realise that something even worse lurks in the eternal dark of the Lost Eyrie of the Demon King?
Dungeon Background
A century ago, a pack of ferocious and depraved harpies dwelt in the Lost Eyrie of the Demon King and terrorised the surrounding area. The Eyrie served as a secure lair for the harpies, as most humans could not reach it.
The place was sacred to Pazuzu—the so-called King of Demons and the harpies’ master. The Eyrie had another secret, however. Deep in its depths, the harpy sorcerer, Gyrtuskarr, opened a small portal to Pazuzu’s Abyssal realm. Gyrtuskarr believed she was descended from her king’s own seed and sought to prove herself to her father by expanding the portal from the Abyss to the Material Plane through bloody veneration and sacrifice. Eventually, a group of heroic adventurers slew most of the pack, drove the survivors far away and put an end to Gyrtuskarr’s insane plan.
For long years, the Lost Eyrie of the Demon King lay forgotten and abandoned. Set halfway up a sheer cliff, it was a difficult place to reach for those without the ability to fly. The Eyrie’s exact location was eventually forgotten, and the place—and its harpy mistresses—gradually faded into lurid and fanciful folklore. The Eyrie lay quiet and abandoned until a new threat claimed it as its own. This new threat—perhaps a young dragon, wyvern or manticore—has begun to threaten the locality and prey on the peasants eking out a living in the nearby settlements.
