[i]Gonad's first thought was that the man had teleported. Occasionally he had encountered enemies that appeared right behind or above him, so the moment the man vanished Gonad would take a sharp step to his right and turn so that he could see if anyone appeared near where he had been. As he did so he'd raise his left hand up as if he were going to give someone a wave. The possibility existed that the man had turned himself invisible, but in Gonad's experience those who did that suffered temporary blindness from having their retinas become see-through.[/i]
