During the commencement ball for the Atonement Trials, Draven was wearing fancy formal clothes and a cape. A cape that would get tangled up in his wings if he tried to fly. He explained that it was a statement. A way of showing others that he is so powerful that he wouldn’t even need his wings to win if someone tried to attack him. But now, he’s not wearing a cape. He’s not even wearing fancy formal clothes. Instead, he is wearing armor. Which means that he considers this banquet so dangerous that he can’t afford to waste any of his advantages.
