A majestic depiction of Excalibur, the legendary sword, embedded in a stone at the center of a mystical forest. The sword's blade gleams with an ethereal light, etched with ancient runes that glow faintly. The hilt is adorned with gold and jewels, radiating an aura of power and destiny. Surrounding the stone, towering trees with twisting roots create a natural cathedral, their branches forming a canopy that lets in beams of divine light. The atmosphere is charged with magic, as faint mist swirls at the base of the stone, and fireflies dance in the air, emphasizing the mystical allure of the scene.
