Who are the new kings and queens of Narnia?

At the end of The Chronicles of Narnia: The Last Battle, Peter, Susan, Edmund, and Lucy Pevensie are no longer able to return to Narnia. Instead, four new people are crowned as kings and queens:

* Tirian: Tirian is a talking horse and the last king of Narnia before its destruction.

* Jewel: Jewel is a talking squirrel and Tirian's wife.

* Roonwit the Centaur: Roonwit is a centaur and the High King of Narnia after Tirian's death.

* Shasta: Shasta is a talking horse and the adopted son of Arsheesh, a Calormene nobleman. He becomes king of Narnia after Roonwit's death.
