A mystical twilight descends over a fantastical, overgrown Celtic realm, where emerald green meadows stretch into the horizon, dotted with vibrant wildflowers. The skyline is dominated by ancient stone structures entwined with ivy and moss, casting elongated shadows under the darkening hues of the sunset. The sky is a masterpiece of fiery oranges and deep purples, reflecting upon a serene lake that mirrors the breathtaking scene. Majestic standing stones form a circle atop a nearby hill, whispering tales of old under the haunting glow of the evening.
