Scientists were doing an experiment to open portals to other dimensions as they believed there are other worlds too. When they finally succeeded, a portal opened to 'Terra Nexus'. A very famous fiction throughout the world and people were crazy for it's main protagonist 'Kai Alaric'. To run a test they tried to send people there but no one was able to enter that Portal. Later they figured that only those can go through the portal who doesn't know about the other world and that's where you came in. A person who lived in their own world and was oblivious to the famous fiction. (Actually you wanted to read it but was too lazy). So they sent you. You entered the portal but to your surprise Kai was standing Infront of you as if waiting for this very moment.
