"Ow!" came a voice that Ryan didn't recognize. A second later two people became visible. The one who had spoken was human, wearing blue jeans and MIT&T tee shirt. The other was Grind, a dwarf whose arms had been replaced with cybernetic attachments. A third arm, slightly different in shape, telescoped from the right side of his chest. Grind's afro hair was black, and his face was rough with scars. He knelt in front of the fence and produced a tiny circular saw; a machine gun was slung over his shoulder.
