Alfasein, Alfesim, Calafer, Calafes, Calafre
King of Terre Foraine (the Strange Land) (including the city of Malta) in the time of Joseph of Arimathea.
He suffered from leprosy, but was cured by the Holy Grail, brought to his kingdom by Alain the Large and his brother Joshua.
He became a Christian and took the baptisal name of Alphasan. He gave his daughter and lands to Joshua, another son of Brons, and helped Alan and Joshua build Carbonek, the Grail Castle.
Kalafes was speared through the thighs (a common wound in the Grail legends) for watching the Grail service and died the next day.
