Goel and a Canon Warden

My latest character, Goel Cousland, is the capstone of my exploration play. Between Seth, Killigan and Joel, I will have done at least Origins with each class, and done >90% of possible things in the game (romance with Zevran as an example of something I haven't done). After I've finished him off, through either beating Witch Hunt or getting too bored of his character, I plan to move to my canon Warden. My experience with Goel will help to determine what my plan is for the canon Warden, but at the moment I'm thinking of a Human Mage, with a morality a little less spotless than Seth.
