Editing Gwydion (section)

===War with the South===
[[Gilfaethwy]], nephew to the [[Kingdom of Gwynedd|Venedotian]] king, [[Math fab Mathonwy]], becomes obsessed with his uncle's [[virgin]] foot-holder, [[Goewin]]. His brother Gwydion conspires to start a war between the [[North Wales|north]] and the [[South Wales|south]]. To this end, Gwydion employs his magic powers to steal a number of [[Annwn|otherworldly]] pigs from the [[Kingdom of Dyfed|Demetian]] king, [[Pryderi]], who retaliates by marching on Gwynedd. During the war, while Math is distracted, the brothers return home and Gilfaethwy rapes Goewin.<ref>{{Cite web|url=http://www.maryjones.us/jce/gwydion.html|title = Gwydion}}</ref>

Pryderi and his men march north and fight a battle between Maenor Bennardd and Maenor Coed Alun, but are forced to retreat. He is pursued to Nant Call, where more of his men are slaughtered, and then to Dol Benmaen, where he suffers a third defeat. To avoid further bloodshed, it is agreed that the outcome of the battle should be decided by [[single combat]] between Gwydion and Pryderi. The two contenders meet at a place called ''Y Velen Rhyd'' in [[Ardudwy]], and "because of strength and valour and magic and enchantment", Gwydion triumphs and Pryderi is killed. The men of Dyfed retreat back to their own land, lamenting over the death of their lord.
