Mystical Pyramids and Celestial Wonders

Additional Prompt:  A mystical portal in the shape of an ancient Egyptian arch with a glowing eye symbol at its peak, set amidst a desert oasis with palm trees, backed by pyramids and a mountain range. A cascading waterfall flows through the portal from an unknown source, leading into a serene river below. Above, a massive purple planet with rings looms in a starlit sky dotted with smaller celestial bodies, while two smaller planets align with the apex of the arch, emitting beams of light. The setting is magical, blending elements of sci-fi and ancient wonders in a harmonious landscape during what appears to be twilight.
