Cadwallōn Lōf̃hir

Cadwallōn Lōf̃hir ab Ēnnewan was king of Gwuynedd.

Biography
After his father's death, he inherited most of his kingdom. His brothers were vassalised to Gwynedd, and his cousins continued to be so. His influence in the whole of North Wales gave him the nickname Lōf̃hir, long hand, describing his influence's long reach.

In 500 AD he launched an attack on the Irish colony in Anglesey, led by Serigi. He was accompanied by his son Maylgun and three of his cousins, whose small kingdoms were vassalised to his.

In the same year, they had finally defeated the Irish in one last battle. As the fleeing Irish clambered on their boats to escape, Serigi stood and fought. Cadwallōn personally slew him in battle.
