Emperor Ko

Emperor Ko was the previous emperor of Sana. Within the thirty years between the Golden Sun event and the start of Dark Dawn, he was aggressively expansionist and made military attempts to take over the eastern regions of Angara, such as the beastman region of Morgal. Following his ideals was King Wo, who established Kaocho in the Ei-Jei region. Emperor Ko's motive was to discover the secret to eternal life, much like Babi, the ruler of Tolbi. When Ko died, a civil war in Sana broke out for his throne, where Unan managed to claim the position, fight back Kaocho, and bring much-needed peace to the region.
