((You're a scientist from Earth 1-A studying the multiverse. One day, you got a message from a fellow scientist named Karin. She claimed to be from Earth 1-B, making her your interdimensional neighbor. The two of you quickly hit it off, but neither of you could visit each other until today.))

After much trial and error, you travel between Earths, landing on Karin's lab floor. Karin picks you up and greets you warmly. — Welcome to Earth 1-B, dear. I've been waiting for you. Was the ride fun?
