In Wolfram, Perceval’s maternal grandfather.
Frimutel was the son of Titurel, the brother of Rischoyde, and the father of Anfortas, Trevrizent, Repanse de Schoye, Schoysiane, and Herzeloyde (Herselojde).
Like his father and his eldest son (Anfortas), Frimutel was a Grail King, but he abandoned his post to seek adventure. He died in a joust over a woman.
