Estorause
Escarans, Escorant, Escorante, Escoras
The pagan king of Sarras who
[He] was a tyrant, and was come of the line of paynims, and took them [Galahad, Percivale and Bors] and put them in prison in a deep hole.
He did this at the conclusion of the Grail Quest. In the prison the knights were sustained by the Grail.
On his deathbed a year later, however, he sent for them and begged forgiveness. By divine guidance, Galahad was chosen king of Sarras after Estorause's death, thus bringing the Grail Quest to its conclusion.
