Like many figures from the Brythonic Heroic Age, Eliffer is quite obscure. He is mentioned in some of the pedigrees for men of the north, the Annales Cambriae, a handful of triads, and some poetic references. Many of these references revolve around the ‘Sons of Eliffer’ sometimes Peredur and Gwrgi of Ebrauc directly, sometimes a vague reference to more. Tread carefully, we will be speculating a bit in this, if that’s not to your tastes this article is likely not for you.
