A few times, when she had expended a spell to detect a pocket of fresh water beneath them, she had called upon the raw force of her old magic to draw it up. They had prepared well, but nopony complained about more fresh water. It was only when the illusions began that they started to have trouble. Illusions of a road or town in the distance, the sound of trickling water from just over the next rise, shouts for help inexplicably heard coming from behind dangerous looking rocks. That was when her 'friends' proved to be useful. More than once she had been warned off from paying attention to the false visions, guided this way or that when they encountered a specific illusion. Sometimes she had been stopped in her tracks, forcibly by the pair of changelings, and when she snapped at them, they had revealed how she had almost walked head first into a dark chasm to fall her death.
