Adar Llwch Gwin

'Birds of the Wine Lake'

Drudwas ab Tryffin had three birds and he sent them to kill the first man who came to the field of combat - the place where he were to meet King Arthur whom he challenged to single combat.

His sister, who was Arthur's mistress, delayed Arthur which resulted in Drudwas himself being the first on site. His griffins didn't recognize him, so they attacked and tore him to pieces.
