Olivia was instantly overwhelmed. She had seen this once before—the city that rose above her into eternity, tiered layers somehow inverted, existing in dimensions her mind could not comprehend. Structures and people and vehicles as diverse as her imagination, and many more she couldn’t imagine. They seemed to reach well beyond where a planet’s atmosphere would be. Buildings overlapped, melting into each other without anything to unify their behavior. Billions of creatures conversed, horns blared, music played, food cooked. Everything that was civilization, but more. This was what Earth might’ve looked like in a million years.
