Thinking obliquely of Ged's boat in Earthsea,(just to distract you) which king looked far?
No worries, Far; you're better with names than I am, anyway. As a matter of fact, the magic system of Earthsea was the first thing that came to my mind after your very first challenge here. I remember thinking "I bet he'd love EarthSea."
So, knowing this penchant for names, I've more than a bit of doubt about my answer, which seems too obvious...
But when Inziladûn acceded to the sceptre, he took again a title in the Elven-tongue of old, calling himself Tar-Palantir, for he was far-sighted both in eye and mind, and even those that hated him feared his words as those of a true-seer.
