A mystical dusk casts a mysterious glow over an ancient, overgrown Celtic realm, where vibrant green grass and an abundance of wildflowers paint the landscape. Looming shadows dance across the ruins of an old kingdom, as the fading light of the dark sunset creates a tapestry of deep purples and oranges in the sky. Towering trees with twisting roots reclaim forgotten stone structures, whispering secrets of an age long past. The air is rich with the scent of blooming petals and earth, with flickering fireflies adding a touch of magic to the ethereal scene.
