Design an architectural structure that evokes fear, mystery, and unease. The building should feature sharp, jagged edges, asymmetrical towers, and twisted, unnatural shapes that challenge the viewer's sense of stability and safety. Imagine dark, weathered materials like obsidian, blackened steel, and cracked stone. The windows are narrow slits or glowing red openings, suggesting an ominous presence inside. Surround the structure with eerie, mist-covered landscapes, with dead trees and jagged rocks. The atmosphere is dark and foggy, with unsettling shadows cast across the architecture. The overall aesthetic should blend Gothic horror with surreal, Lovecraftian influences to create a haunting visual experience.
