Roonwit

Roonwit was a Centaur who lived in the last years of Narnia. Like other Centaurs, Roonwit could read stars. He was a friend of King Tirian. He was killed when he was hit by a Calormene arrow during the Cair Paravel Massacre. Although later during the Battle of Stable Hill, all those they thought were dead were revived including Jewel the Unicorn and Roonwit himself. It is not mentioned if he was left in the dead Narnia or entered the second Narnia. Though it's most likely to be the latter.
