Bern

Description
Lord Bern was one of the Seven lost Lords and a Telmarine lord who opposed Miraz. These lords did not fear the oceans or forests, unlike most Telmarines, and were of the few who respected the legends of Old Narnia, or Narnia before the invasion from Telmar.

Biography
"I came thus far with my six fellows, loved a girl of the islands, and felt I had had enough of the sea. And there was no point in returning to Narnia while your Majesty's uncle held the reins. So I married and have lived here ever since."

- Bern Bern and six other lords were sent to "explore the seas beyond the Lone Islands" by King Miraz in an attempt to get rid of them. Lord Bern remained behind at the Lone Islands when his companions continued on toward the eastern end of the world. He bought slaves from the slave trader Pug and freed them, possibly in repentance for his early abandonment of his friends.

King Caspian X, during his famed journey over the eastern seas, was purchased as a slave by Lord Bern after being captured by traders before any of the island dwellers were aware of his true identity. Bern bought the king because he reminded him of Caspian IX, the father of Caspian X, whom the Narnian lord had served prior to the king's death and his exile by Miraz. King Caspian revealed his identity to Lord Bern, who then assisted the king in reestablishing a Narnian presence on the islands. Upon his departure, Caspian threw out the present, corrupt governor and made Lord Bern Duke of the Lone Islands, as he "had enough of governors."

Film Biography
In the film adaption, Miraz had tried to kill Bern and the other 6 lords, so they fled to the Lone Islands. It was there that they discovered that a mysterious Green Mist had been sighted in the East, where numerous people were disappearing in it. The 7 lords made a pact to find the source of the Mist, and destroy it. Each set sail, but unfortunately, before Bern could leave, he was captured by the corrupt government in Narrowhaven, and was imprisoned in a jail-cell where he must have remained ever since, before Caspian and the Dawn Treader liberated him. The rest of the lords had long since left, to continue their quest for the Mist.

Bern had with him an old Narnian sword, originally from the Golden Age of Narnia, which he had kept hidden in a cave for years. It was one of Seven Swords, originally a gift from Aslan to Narnia, to protect it. It had been given to him by Caspian IX, though how he got it is unknown.

It can be presumed that when the Dawn Treader left Narrowhaven, Caspian left Bern as its new Duke, as he did in the book, to rule over it wisely.

Trivia

 * Lord Bern's name probably stems from the Old English word "berne", which means "warrior": a classification that fits Lord Bern as a participant in the re-conquest of the Lone Isles.
