Soon Kim is the founder of the Sapphire Guard. While it's possible that he is also the founder of Azure City, it's never stated anywhere.
Also, I really want to post Miko's story, but I really really don't want to break my copy of No Cure For The Paladin Blues to get the 2 or 3 bonus strips that show how human and inhuman Miko is.
Aaron "The Mad Whitaker" Bourque; Miko is my second favorite minor character in the strip. My favorite is the scarf-wearing Shadow Dancer. (Fruit Pie the Sorcerer is my third favorite).
