Religion: is the most crucial part of society and plays an important role in Willem’s life. Willem can be described as a straightforward man who, according to many, serves only to strengthen the rule of the church. He resigned the rank of officer in 377 in order to devote himself to study of the holy scriptures and has written two editions of his works “My Exclamation” one at Trinsic in 387 edited by scribe Theodorus, the other at Yew in 395, published under the direction of Father Donovan, of the Guardsmen militia Templi order.

Willem's political and religious opinions are expressed somewhat crudely, and lent themselves to a somewhat fanatical interpretation. Although he managed to secure a high rank within the chain of command within two years, his crude and fanatic religious opinions were not shared. It was of deliberate purpose that he entered into opposition to those less faithful. He dreamed of showing a devotion to the Church equal to that of the great Templars; but alas he had not the same genius, self-control, and tact. He is a profound and keen defender of the doctrines of the Church. He holds that the doctrines of the church should be embraced at once by faith, through an act of the will.

His father, Johanus Koning, was from Yew; his mother, Antoinette, from Vesper. Though his family hails from Vesper, Willem is a thorough Yewsman, full of national and local patriotism. His father, a fisherman, gave him a thorough education and placed him and his younger brother Francis under the monks of the Abbey of yew in his tenth year. He would later leave the abbey after having found out that the way to virtue taught by the monks was not the perfect one. His uncle, a great sergeant in the local militia, took an interest in the boy and introduced him to the arts of hunting and sword fighting, in which he became very proficient. In his eighteenth year, in spite of the opposition of his family, which was finally overcome by the intervention of the abbot, he entered the ranks of the militia. On his nineteenth, he was employed under the Master Corsair of the militia, and so learned about leadership and political business. At twenty-one he was elected sergeant and at twenty-five he succeeded the Master Corsair. He reformed the corsair division, and established trade routes along the coast of Britain.
