After defusing another flash point in the ongoing fracas between the Winfiel Kingdom and the Church, Col and Myuri are more than ready to take a breather. Of course, the world has other plans for the infamous Twilight Cardinal. As the pair leisurely make their way to a famous monastery, they stumble upon a fallen squire who carries a desperate plea for help. With the world’s strongest holy order of knights on the brink of dissolution and Col apparently to blame, there’s no time to waste!
