For Alien Space Bats. The Alien Space Bats are creatures that make possible things that would be implausible from little changes from OTL. For example, Alien Space Bats have mind control powers to make leaders (and their advisors, staff, and followers) to take decisions they would have never taken if sane. They can also swap people(s), territories and objects (including you) between places at a given time, or even across time (for example, they can send the contemporary island of Nantucket hundreds of years in the past, as in Island in the Sea Of Time), or insert your brain into the one of a historical figure (as in you wake up as Napoleon the day before Waterloo).
