Daedalus is a crabby, patronizing, mad genius. He's also heartbroken and guilt-ridden over the loss of his son Icarus. Yes, that Icarus - the one that got too close to the sun. You see, Daedalus built the wings that Icarus used, wings of wax that melted in the sun. So forgive him his curmudgeonly nature - his allies try to, for his intellect and prowess for invention is unparalleled.
