Caspian X

Caspian the Tenth is a character in C.S. Lewis' The Chronicles of Narnia, and features in three of the seven books. In The Movies he is played by Ben Barnes

In The Books
As a young Telmarine prince, Caspian was heir to the throne of the kingdom of Narnia. His father, Caspian the Ninth, was murdered by his younger brother Miraz. When Miraz's own son was born, he attempted to kill Caspian, who fled the castle and into the woods, where he encountered the Old Narnians - dwarves, fauns, centaurs and Talking Animals, whose ancestors were murdered by the Telmarines who conquered their kingdom and whom the Telmarines believed to be extinct. Caspian took up their cause, but was in need of help to take his throne from Miraz. He blew the magical Horn of Queen Susan, and summoned the four Pevensies back into Narnia. With the assistance of the ancient kings and queens, Caspian and the Narnians defeated Miraz. Caspian was crowned king.

Three years later, Caspian sailed to the End of the World on his ship, the Dawn Treader, accompanied by King Edmund, Queen Lucy, and their cousin Eustace. Along the way, he met the star Ramandu and his daughter, whom eventually accompanied Caspian back to Narnia. They married and had a son, Rillian, who disappeared about twenty years later shortly after his mother died of snakebite. Caspian spent years searching for his son, to no avail.

As an old man on his deathbed, Caspian was finally reunited with Rillian after the prince was rescued by Eustace and his friend Jill Pole. Caspian then died and woke in Aslan's Country, Narnian heaven.

In Badfic
In badfic, Caspian is often maligned by being made wangsty and a complete wimp who needs Peter Pevensie to come along and save the day. Either that, or he is made out to be an arrogant brat. He is often paired in het fic with Susan Pevensie thanks to the crowbarred-in romantic subplot of The Movies, or in slashfic with either Peter Pevensie or Edmund Pevensie. Or both.
