The more Oliver saw through her eyes, the better he could feel the void, and the distortion that was caused by that overwhelming quiet. He felt like he could map the space around it. The feeling of wrongness grew to such an intensity that it almost made him feel sick. He turned his eyes, finally, in what seemed to be the right direction. He looked at empty space head on, and went dashing towards it. His sword ran out, slashing, for no reason at all – and still found nothing but empty air. Empty air, and then a sudden rush of wind, as a creature dodged past it. The slightest swelling of alarm.
That, without Claudia's assistance, he would have never noticed. Making the void move, as unnatural as it was, brought Oliver's sense of nauseous awareness to him all the stronger. He couldn't see the man, but now he was sure he could sense it. Or at least, he could sense whatever it was that allowed him to move as such.
