Imagine a mystical enchanted forest at twilight, where a shimmering, crystal-clear lake mirrors the vibrant colors of an aurora dancing across the sky. Ethereal creatures, such as graceful phoenixes and luminous will-o'-the-wisps, glide silently through the air. In the center of the lake, a small island hosts an ancient stone altar, adorned with glowing runes. Capture this magical world in a dreamlike, ethereal art style, emphasizing the enchanting interplay of light, color, and mystical elements.
