Create an image featuring a majestic creature resembling a mythical beast with iridescent scales, soaring through a vibrant twilight sky. It should be positioned above a rocky formation resembling an ancient arch, adorned with lush greenery and mystical flowers. In the background, incorporate swirling clouds with hues of purple and gold, suggesting a magical atmosphere. The overall mood should evoke a sense of wonder and enchantment, while avoiding any specific brand references.
