The wizard of Arthsea could be a good starting point.

Quote:
Then, with no idea how to deal with his other foe, Sparrowhawk tries to return to the safety of Roke, but the magical, protective Roke-wind drives away the ship on which he is a passenger. He finds what appears to be a safe haven, the domain of one of the Old Powers, but is nearly enslaved by the ancient guardian. He realizes his peril just in time and, taking the form of a falcon, flees yet again.
An icon of a Hawk is what I would use.
