Oreius

"Are you with me? To the death"

- Peter and Oreius shortly before the Battle of Beruna.

Oreius was a Centaur and the Supreme Commander of Aslan's Army against the evil White Witch during the Hundred-Year Winter in the screen adaption.

He helped to rescue Edmund, and trained his to-be-king brother Peter (and Edmund) to use a sword. He was first encountered at Aslan's Camp near the Stone Table.

Oreius was loyal to Aslan, and helped Peter strategise the Battle of Beruna after Aslan's supposed death. He had three swords that he used during the Battle of Beruna, took down General Otmin of the White Witch's Army, and even confronted the White Witch herself, but she turned him to stone before he could harm her.

However, Oreius was later seen at the coronation of the Pevensie children, for he had been un-petrified by Aslan's healing breath shortly there afterwards.

Trivia
Oreius was played by Patrick Kake in the adaption.
