Sir Loholt (also Llacheu) was an illegitimate son of King Arthur by Lady Lisanor of Cardigan, with whom he had a brief fling prior to his marriage. Loholt was both a handsome and noble Knight of the Round Table who entered into a number of adventures. He helped his father rescue Queen Guinevere when kidnapped by King Valerin of the Tangled Wood; and fought and killed a giant named Logrin in the Perilous Forest. Sir Loholt fell in love with Lady Florie of Kanadic and died while in her service.
In the Lancelot-Graal Cycle he was apparently captured by Sir Caradoc of the Dolorous Tower and incarcerated in his prison. There he contracted a rather unpleasant disease, and although rescued by Lancelot he died soon afterward.
