“Once, there was a war known as the “War of the Shadows,” An epic battle between Prince Marth’s heroes and the Dolhr Empire, which ended with the defeat of the Earth Dragon King, Medeus. The warriors who had united under the Fire Emblem returned to their own lands, devoting themselves to the reconstruction of their homelands. Among the nations that made up the “Seven Kingdoms of Archanea”, Gra and Grust were devastated. Altea, Aurelis, Macedon, and Talys were left deeply scarred, and even the mighty Kingdom of Archanea was undergoing restoration. However, in the palace still shaken by war, one important event took place. Hardin, the younger brother of King Aurelis, was married to Princess Nyna, becoming the twenty-fourth king of House Archanea. After ascending the throne, Hardin aggressively restored the country in the twinkling of an eye, and formed a powerful army by gathering many soldiers. He then proclaimed the restoration of the Holy Archanean Empire, and himself Emperor. One year has passed since the war with Dolhr. The world seemed to be moving towards an era of peace. However, unbeknownst to man, the cogs of destiny had started spiraling out of order. It has been a year since the War of Shadows ended. The war-ravaged kingdom of Altea was finally starting to regain stability thanks to Prince Marth’s efforts. Prince Marth’s engagement to Princess Caeda was announced, and the people of Altea rejoiced, sharing their happiness. However… nearing the day of their wedding, an unexpected letter arrived from the imperial palace, containing an imperial edict. "Dear Prince Marth of Altea, In the Kingdom of Grust, now under imperial rule, a large-scale rebellion has broken out. I request your kingdom’s assistance in its subjugation. Your Highness is to lead the entire army of Altea and sortie at once, suppressing the Grustian rebellion.-The Emperor of Archanea" The Kingdom of Archanea was Altea’s suzerain, so its orders were absolute. Forced to comply, Marth ordered the knight Cain to protect his homeland, and together with Jagen, the paladin Arran, and the young, newly appointed knights, left Altea on the Grustian expedition.”
