Envision a mysterious twilight sky casting a dark, ethereal glow over an ancient, verdant Celtic kingdom. The landscape is lush with vibrant green grass and wildflowers, thriving amidst centuries-old stone structures. Vines and ivy overtake the historic architecture, weaving through intricate Celtic carvings and symbols, as a gentle breeze whispers through towering trees. The setting sun paints the sky in deep purples and fiery oranges, its light filtering softly through the overgrown canopy, creating a dreamlike atmosphere that blurs the line between myth and reality.
