Lost Pyramid Civilization in Misty Rainforest

Create a cinematic sci-fi fantasy scene of a lost pyramid civilization hidden within a vast misty rainforest. A colossal stepped pyramid, ancient stone temples, towering obelisks, waterfalls, rivers with boats, lush jungle, and crowds of people blend seamlessly with futuristic grounded spacecraft, giant bipedal mechs, and a glowing blue energy portal inside the pyramid. Begin with a wide aerial flyover, then smoothly push toward the grand pyramid entrance as golden-hour sunlight filters through the mist, contrasting with the portal's vibrant blue glow. End by flying into the radiant portal, fading to white, with an epic orchestral soundtrack and powerful choral atmosphere.
