Hem/Cai

Hem, named Cai at birth is a Minor Bard in the Pellinor series of fantasy adventure books by Alison Croggon. He is the brother of Maerad and like her has amazing Bardic skills. At a very early age, Cai, as he was then known, was taken from his home by a group of Hulls during the sacking of Pellinor. They renamed him Hem, to better fit the realm in which they lived, and spent much effort and energy in trying to pervert him and bring him to the side of the Dark.

If indeed he is, he will be able to do similar feats as she, including conversing in the Elidhu language without needing to learn it. He seems largely skilled in deceptive magery...
