A terrifying and hellish floating city in the sky, surrounded by dark, stormy, and purple clouds. The city, Altakar, is a vision of despair, suspended above the ground with jagged, twisted architecture and glowing purple fissures running through its structures. A massive section of the city is shaped like a colossal skull, ominous and foreboding. Acid- green toxic rivers flow from the city, cascading down in a deadly mist. At its peak stands the dark castle of Desmodan, a menacing fortress with spires reaching toward the heavens. The scene is engulfed in deep shadows and illuminated by an eerie purple glow. Bolts of lightning streak through the dark purple sky, emphasizing the city’s apocalyptic presence. This hyper- realistic depiction captures a cinematic and epic perspective, with intricate, ultra- detailed designs, 8k resolution, dark and moody lighting, night- time setting, film grain, ultra- quality, and a sense of overwhelming dread and otherworldly power.
