It was, for lack of a better term, magic. You've been transported to a whole other world, with a different society than you are used to. Like suddenly being moved to another realm without traveling or preparing.
You are at a computer, a device that is... well it is sort of like magic. It's purpose is to help you do things. One of the things it can do is help you communicate with others like yourself who have been transported here.
My name, by the way, is Julien Boudreaux, at your service.
