Spectral Gothic Landscape Of A Haunted Castle

Ethereal, mystical castle ruins shrouded in an otherworldly, spectral mist, with twisted, organic spires and turrets, inspired by the dark, biomechanical visions of H.R. Giger, rendered in breathtaking, 8k resolution detail, with dynamic, volumetric lighting that casts eerie, flickering shadows, reminiscent of Greg Rutkowski's hyperdetailed, dark fantasy concept art, infused with the elegant, Art Nouveau sensibilities of Alphonse Mucha, and the haunting, surrealistic quality of Jordan Grimmer's atmospheric landscapes, featuring a bold, contrasting color scheme of deep, rich purples and vibrant, golden yellows, evoking a sense of foreboding, mystical energy, perfect for a show-stopping, splash screen art piece that would trend on Artstation, with the level of intricate, detailed craftsmanship and immersive, cinematic atmosphere of an Unreal Engine masterpiece.
