Jewel

Jewel is a noble white unicorn with a blue horn and he was the best friend of Narnian King Tirian. He was gentle with his friends but used his horn as a fierce weapon in battle. Much given to making noble speeches, he was never deceived by the False Aslan. He was killed in The Battle of Stable Hill. In Aslan's Country, which he says is the only world that never comes to an end, he gave the call to go "farther up and farther in!"
