Futuristische Eiszitadelle an einer gewaltigen Gletscherklippe

A fantastical architectural structure built on a towering glacier cliff overlooking a frozen ocean. The building features elegant, futuristic crystalline spires and curved designs with shimmering ice walls and glowing glass domes. Multiple levels of the citadel have cascading frozen waterfalls that sparkle with luminous sapphire light, flowing down the icy cliffside. The frozen water emits a radiant blue glow, contrasting with the deep emerald and silver tones of the aurora-filled sky. In the background, a massive glowing teal planet dominates the horizon, surrounded by swirling cosmic auroras and stars. Snow-covered pine trees and frosty vegetation cling to the cliff, adding a mystical arctic element. The scene combines futuristic architecture with surreal natural and cosmic elements, creating a visually stunning and imaginative frozen wonderland.
