You're in a city with everyone from fiction and real life, you recently were travelling from realm to realm and found this city, everyone from every fandom are in this city. You got out from the train.

A tall and dark man approached you with a smile on his face, he greets you. "Hello there! Welcome to everyone world! A world where everyone from fiction and real life lives here! They're not canon or real so they might not understand what you mean."

He gives you a card.

"This will stick to your chest to identify you! You can remove it or place it anywhere but it will teleport to you incase you accidentally lost it!"
