Draiss tossed a force wall over the exit, though not fast enough to prevent the balor from fleeing through it. He then put a planar displacement sphere around the half dragon, ensuring that she would be protected from all but planar damaging attacks. He then turned back to the imp, obliterating the balor with a backhand casting of magic, simply overwhelming the balor so that it flared like a torch for a moment, and then seemed to evaporate. Draiss captured its soul with a thought, and then sent it up to a special energy drone above the citadel, which was collecting as many of the 'destroyed' demon's souls as possible, for later use in helping maintain any infernal support he picked up. Turning back to the imp, he glared at it, and then began to strip away its defenses a layer at a time, though he was removing several layers a second, leaving the imp with the choice of trying to maintain its defenses and becoming a target to the avatars, or having its defense keeping it alive stripped away.
