The Cult
No cult attaches to Efnysien, and none should be invented: he is a literary figure, the strife-maker of a single branch of the Mabinogi, written down in the fourteenth century from a tale probably composed two centuries earlier. No shrine, festival, votive, or priesthood names him, and the Welsh landscape keeps no grave of his: Bedd Branwen, the cairn by the Alaw, belongs to the sister his deeds helped kill, not to him. The only 'service' the tradition ever paid him was narrative — the Second Branch needs its breaker, and it made him superb at the work. How he was honored is simply not a question the record asks.
