In TA 1650 the Chieftain of clan Corddwallon was Dinglas (Du."Grey Man"). He had been Chieftain for only 3 years but had a reputation as a cunning man who was prone to fits of anger. He was in constant contact with Maben, and considered his counsel over all others. In the 3 years of his rule, the clan had become even more war-like and drawn even closer in it's relations to the Temple of Justice.
