House Kaijitsu is a noble family in Magnimar, formerly known as the Amatatsu family of Minkai. In Minkai, they were one of the five families Shizuru granted a divine mandate to rule. Pursued by a group of oni called the Five Storms who were intent on their destruction, they fled their homeland in the mid-47th century AR. They left the continent of Tian Xia and finally settled in the Varisian city of Magnimar, where they became part of that city-state's nascent nobility.
