I know that whatever they have done obviously didn't work. That means that more research is required. That research needs to be done by people with magic. Therefore, I was seeing who has magic and which person with magic wants to help.
How do you know that it will wait? Has anyone returned to their time and place? Have they returned here after going back? Do you know if you can return to the exact same moment? What about not returning at the same time, does that create a different dimension? If anyone knows, I'd love to hear it. Any and all knowledge will make research easier.
In fact, where is here? How are we kept inside? How does the hotel move? Are we on earth?
