From high above, the Nightmare Keep loomed like a dark stain upon the desolate landscape. Its jagged towers and twisted spires pierced the sky, shrouded in perpetual shadow. The battlements, carved from blackened stone, seemed to absorb the light, giving the fortress an eerie, foreboding presence. Below, a labyrinth of crooked walls and hidden courtyards sprawled out, surrounded by a moat of murky, stagnant water. Twisted vines and thorny brambles crawled up the walls, adding to the fortress's menacing allure. The surrounding forest, a tangle of gnarled trees and thick underbrush, encroached upon the keep, as if nature itself sought to reclaim the cursed ground. From this height, the Nightmare Keep was a fortress of dread, a sinister stronghold that whispered of ancient evils and unspeakable horrors lurking within its shadowy depths.
