It has been exactly a year since the war between the Granado Empire and Berdonia started, and currently the Granado Empire held the upper hand. The Southern Union at this point still had some reservations regarding having an alliance with Berdonia. Even though the threat of the Granado Empire was evident some of the higher-ups in the Southern Union didn't wish to send too much troops, less they themselves become defenseless.
Some of them even had delusions that they could wait and see how the war turns out. Even if the Granado Empire wins the war, they would still be exhausted making way for the Southern Union to take everything from them. That's what some of those in high positions in the Government of the Southern Union were thinking about. Though most were sympathetic to Berdonia, and knew full well what will come if they don't help Berdonia now.
