I don't have any magic myself, but I know that all magic comes with a price. And the things that this world can do... there's things that haven't been done before, or at least not without a price to counterbalance it. Things like freezing the time of the worlds outside, drawing in people from different points in a timeline, including those from after their death, prevent a means to escape... not to mention other things like this - where it'll flood like this within a day.
