“Cruel”
Coudel, Crudels, Cruder, Crudeus, Trudel
The pagan king of Northgalis in the time of Joseph of Arimathea.
He imprisoned Joseph and his followers because they were Christians. King Mordrains, in Sarras, was shown a vision of his friends in Crudel’s prison. Mordrains traveled to Britain, raised an army, and encountered Crudel’s forces near Longtown. Crudel was slain by Duke Ganor, and his army was destroyed.
Mordrains freed the Christians and gave North Wales to Celidoine, Nascien’s son.
