In 1257, the Karad Empire fell. King Ragnar III of the Nords led the Nords to invade the northwest region of the Calradian continent from the North Island and established the Raven Crown Dynasty. The capital was Sargos. After disputes with the other five countries on the Calradian continent, the Nord Kingdom fell into defeat after two kings. Finally, under the raging offensive of the Salander Sultanate, the city of Sargos was destroyed and the Nord Kingdom was destroyed.
