Root

Root (ルート, Rūto) is an elder wizard and servant of the King of Enlad in Tales from Earthsea.

Story
One of the king's wizards, Root is older and wiser than most of the king's other advisers. The king goes to him with questions about magic. It is Root who explains the nature of the kingdom's latest problems, although he doesn't know why it has become that way. He seems to be knowledgeable on the subject of dragons.
