Create a highly detailed dark fantasy scene set in a vast desert under a twilight sky. Depict a mystical ruin partially buried in the sand, with ancient pillars and glowing magical inscriptions etched into the stone. The sand should appear windswept, with shimmering particles reflecting the fading sunlight. Add mysterious figures in the distance, cloaked in shadows, and incorporate subtle magical energy flowing through the air, creating an enchanting yet desolate atmosphere.
