Unofficial capital building of the Sky Planes. Tatsuki Castle was built by Mishiyo Tatsuki‘s grandfather, one of the original inhabitants of the Sky Planes. Mishiyo was the first Sylph of the Tatsuki family, and when he founded the Shadow Clan, this castle became the clan’s school and dojo. Mishiyo now lives in the castle and runs the nation-state government from there.
