Jace is an intellectual, very practiced in magic. He loves to learn, and travels for that very reason. His magic is as eclectic and diverse as could be imagined, and he has dabbled in most arts. If he has something to learn, he will learn it (easily).
Jace Beleren, Astral Traveler Servitor
He has offered to pass on his knowledge to you, and also take you to some of the realms he has learned from so that you may learn the same way he did. He has an astonishing memory for realms, and will definitely prove to be an amazing navigator with a good idea of what to do in any situation.
