[@Ozerath] Paladin seems more like a class.  Monster hunter might work, or perhaps protector/guard -- he keeps the places people are safe, and gets rid of threats.  Honestly I don't see an issue with being a knight/paladin in the sense of it's just a generic concept -- Elian's a healer, and I've seen people use thief as profession.  But if knight isn't okay, paladin probably isn't either, save that it also incorporates a church or deity he works for....*waffling*
