Well Kando and kandosii are forms of "noble," and ad means "man," but you might want alor for "leader" instead.
You could try: Kand'alor, or Kando'ad.
Also, be strongly encouraged to drop by the intro thread and put down your name, age, and social security number, or the mods will beat you with hammers!
(Well, they probably won't, but you should post your social security number anyway, just to be, um . . . safe.)
