Tanner detects a mysterious presence outside the room as he starts to leave, "Hmm," he turns around and shines his flashlight on the wall to see if there was anybody wearing stealth, the light bends and a near invisible figure is seen next to the entrance, "HEY! STOP!" he yells. He draws his combat knife and throws it at the invisible being but misses and the knife winds up stuck in the wall. The invisible entitiy disappears, probably into the room where he just came from, "OH S***!"
(Is this good?)
