His first clash came when he was hunting near Beyond and saw some white hounds with red ears cornering a stag. He drove them off with his own hounds, only to be confronted by ARAWN, owner of the hounds, the land and of course the stag.
Acknowledging and apologizing for this terrible breach of etiquette, PWYLL agreed to a job swap for a year whereby he ran ANNWN, and ARAWN ran PWYLL’s Kingdom, with the proviso that PWYLL was expected to have a go at ARAWN’s enemy Havgan who could only be killed by a single blow. And there was to be no wife-swapping.
PWYLL did well and zapped Havgan. Then he realized he had missed out on the wife-swapping deal. Feeling it was time he was married, he wed RHIANNON. Then things went a bit haywire.
