A character in The Chronicles of Narnia, written by C.S. Lewis. Prince Rilian is the son of Prince Caspian, and rightful ruler of the kingdom of Narnia. He is captured while trying to avenge the death of his mother Ramadu and imprisoned by a witch using the magic of The Silver Chair. He is later freed by Eustace Scrubb and Jill Pole after the two are sent to quest for his freedom by Aslan in the book titled (strangely enough) The Silver Chair.
