Dilianfer of Ireland

Rilanfer

The king of Ireland during Uther Pendragon’s reign.

He attacked Felix, the king of Cornwall and Lyonesse, and sacked the fortress of Tintagel. Through his victory, he established the custom by which Cornwall paid an annual tribute to Ireland. This custom ended when Tristan slew Morholt, Dilianfer’s son.
