"An earthquake strikes a bustling city, and a massive crack opens in the center of a busy park. As the camera descends into the fissure, it reveals a hidden, thriving underground civilization. Giant, bioluminescent mushrooms light the way, and strange humanoid figures with glowing eyes move about their homes carved into the rock. Rivers of liquid crystal flow through the caverns, and ancient machinery hums faintly in the background, hinting at advanced but forgotten technology. The camera explores this lost world before retreating as the crack begins to close."
