GURPS: Casus Belli
Einion Yrth ap Cunedda
Heir-Apparent to King Cunedda
Einion ap Cunedda, also known as Einion Yrth (Welsh for “the Impetuous”), is one of the sons of Cunedda. He traveled with his father to north Wales in the early 450s to expel Irish raiders from the region. As the king’s only surviving son, he is the heir-apparent.
Interestingly enough, his nickname – the Impetuous – appears to be ironic in nature as a more patient man likely does not live.
