It is a fine day in the realm, the sun shines, birds are chirping... but something looms on the horizon! What might it be? Before you know, alien spaceships are roaming the planes!! And they seem to want... to sell the royalty intergalactic encyclopedias?!
Well, that can't be! King and Queen Rock are having their third dinner at the castle and don't want to be disturbed, so take the command of the defenses of the city and drive those pesky aliens out!
