morfran eil tegid (morfran son of tegid) appears in several of the welsh triads. in triad 24 he is recognized as one of the "three slaughter-blocks of the island of britain", while triad 41 celebrates his horse guelwgan gohoewgein (silver-white, proud and fair) as one of the "three lover's horses of the island of britain". other manuscripts attribute this horse to drystan (tristan) and ceredig ap gwallawg. in other triads he is associated with sanddef, whose beauty is as notable as morfran's ugliness. in a triad preserved in the prose tale "culhwch and olwen", morfran and sanddef are named as two of the three men who survived the battle of camlann, in morfran's case because his ugliness led everyone to believe he was "a devil helping, for there was hair on his face like the hair of a stag." this triad was adapted in the 15th-century triad collection known as "the twenty-four knights of arthur's court"; the pair are two of the "three irresistible knights", as their peculiarities made it "repugnant to anyone to refuse them anything."
