Arutha is my favorite Feist character. I've read more of Feist's books and each have great characters, but Arutha still has this awesome style and character about him that can't be beaten. He was also a character from the Betrayal at Krondor game that I played when I was younger, which was my first introduction to Feist. He was a favorite character then also, despite his apparent moodiness (but I tend to like moody little stormclouds :tongue:).
Arutha is followed very veery closely by Jimmy the Hand.
