Shasta, later known as Cor of Archenland, is a fictional character in C. S. Lewis' Chronicles of Narnia. He is the principal character in the fifth book published in the series, The Horse and His Boy. The book's events, however, are chronologically third in the series. He also appears briefly at the end of The Last Battle, the seventh and final book in the series. Born as the eldest son and heir of King Lune of Archenland, and elder identical twin of Prince Corin, Shasta/Cor was kidnapped as an infant and raised as a fisherman's son in the country of Calormen. In The Horse and his Boy (the events of which all occur during the reign of the four Pevensie children in Narnia, an era which begins and ends in the last chapter of The Lion, the Witch and the Wardrobe), Shasta/Cor escapes to freedom, saves Archenland and Narnia from invasion, learns his true identity, and is restored to his heritage. Shasta's companions on his journey are the talking horses, Bree, and Hwin, and the Calormene Tarkheena, Aravis. Shasta/Cor grows up to become King of Archenland, marries Aravis, and fathers the next (and "most famous") king of Archenland, Ram the Great. Source: Wikipedia (en)
