As a matter of fact, that if you Demon guys want to raid the resources collected on the Battle of Ruthria, they are indeed in Celestia, since the fact of the resources being taken to the capitals was written on the OP of the last battle and was even used to foil one of Miyu's plans.

Now, if you are attacking a random storage facility you can choose where it'll be. However, if you are going to do that, why not have said facility be the place where the next battle will be happening in first place and cut is some corners?

You can even say that you launched a surprise attack, beginning the battle before it was supposed to and have an upperhanhd on the conflict. As long as as [@TheWindel] and [@Lonewolf685] agree, of course.
