Well, what I based Kellus's character on is the Codex Alera series, so if you've read that you'll get a lot better idea of what he's capable of.  Most of his furies are aligned with the various elements (you've seen most of them, but he has a water fury and a metal fury that he hasn't called on yet), but due to a run-in with a rather nasty group of sorcerers, he effectively has a '7th' fury, one comprised of spiritual/shadow energy.<br/><br/>The tatoos on his arms are actually part of a much larger design that covers most of his chest, forming a ward that was used to forcibly bind the spirit fury to him.  It's primary ability is to draw out the soul of another and consume it, adding it's life-force to Kellus's; he's actually a lot older than he looks.  It can also see into a person's soul, to a degree, and has a couple other abilities, but it's really obvious when he's doing so, which is why he hasn't done so yet.  Plus, he's not really comfortable using it around people that he doesn't know very well, as it can tell him things about people that he doesn't want to know.<br/><br/>On a second note, when did I say that Kellus would refuse?<img alt=":D" src="./images/smilies/icon_mrgreen.gif" title="Very Happy"/>
