A towering icy citadel built entirely from blue ice, prismarine, and sea lanterns, rising within a 16x16 base and 32 blocks tall. The fortress features cascading snow layers along its walls, glowing crystal-like towers, and a grand staircase leading to an arched entrance. Passive mobs like wolves and polar bears roam around the base to give life to the scene. The design should feel like a mystical movie set, shimmering in daylight, with no floating blocks or forbidden items.
