In 1360 Otto, Lord of Arkel succeeded his father. He quickly came to favor with Count Albert of Bavaria. In 1364 John of Arkel became Bishop of Liège, and in 1366 Liège annexed the County of Loon. This way John of Arkel became Dirk Loef's liege lord for Horne and Kortessem. This was a very dangerous development for Dirk Loef.
