PROMPT:
Create a mesmerizing astral gateway image that transports viewers to another realm, set against a radiant, electric blue celestial backdrop. Incorporate vibrant, clashing colors like emerald green, amber, and turquoise to evoke an otherworldly atmosphere. Depict a shimmering, iridescent portal with swirling, ethereal tendrils that appear to pulse with an inner light. The gateway's framework should resemble an ancient, mystical architecture, with intricate, glowing runes etched into its surface. In the foreground, include a few, strategically placed, glowing, crystalline structures that seem to be drawing energy from the portal. Ensure the overall image exudes a sense of mystique, wonder, and adventure, while maintaining a photorealistic quality that invites the viewer to step into this fantastical realm.
