Corin

Corin, known as Thunder-Fist, was a Prince of Archenland and son of King Lune. The twin brother of Cor, Corin was younger by twenty minutes. Because of a prohpecy that said Cor would save Archenland from a terrible threat, a Calormene agent kidnapped Cor. As the only child left of King Lune, Corin became the heir to the Archenland throne.

Corin later met his brother (who was known as Shasta) while joining Queen Susan and King Edmund of Narnia on a diplomatic mission to Tashbaan. He helped Shasta escape the city during his own escape. He encountered Shasta again in Narnia, as Kind Edmund and Queen Lucy led an army to Archenland to aid Kind Lune in the battle against the Calmorenes. It was after the battle ended that Shasta was revealed to be Corin's twin brother.

Due to Cor return to Archenland, Corin lost any claim to the throne, much to his delight as "It's princes have all the fun".
