Air Combat

Every country had their own trump card in the air. For instance, the Munn Kingdom owned floating magic warships that sailed in strong gales and the Country of Darkness possessed a massive ghost fleet. However, there was a necessary restriction for these trump cards—they would never be dispatched unless their country was invaded. Of course, this wasn't a restriction based solely on contracts and official documents, but also involved problems of their own instead. It was just like how floating magic warships in the Munn Kingdom had to rely on the power of the strong gales in order to hover and sail in the air. The Country of Darkness's ghost fleet also needed the presence of a thick death aura in order to remain afloat in midair. If the death aura wasn't dense enough, the massive ghost fleet couldn't be sent out at all, which was also the second reason that limited the mobilization of the ghost fleet.
