Shiro Akiko was the palace built by Isawa, who gifted it to his daughter Isawa Akiko to honor the betrothal of Akiko with Asako Sagoten. The wedding was broken, and in the year 72, Sagoten foolishly attempted to use the Isawa's Last Wish to recover Akiko's love. The Wish flared out of control destroying the palace and all who were there. No vegetation grew there since and the Phoenix avoided the area.
