A massive, crystalline pyramid floating above a calm, mirrored lake at twilight. The pyramid is filled with a swirling aurora of colors, reflecting the setting sun’s golden rays. Tiny, luminous orbs drift inside, like stars caught in a celestial current. Beneath the pyramid, the lake’s surface shimmers, reflecting the vibrant hues of the sky. Around the lake, tall, shadowy trees stand silent, their reflections merging with the scene. The air is thick with a gentle mist, adding an ethereal, dreamlike quality.
