Harry only had an hour, so he pushed forward, swimming through the water far better than he’d ever done before. He was practically flying, gliding past the tick green weeds and rocks with the ease of an aquatic animal. Harry was a little disturbed by the silence that pressed against his ears, and despite his better vision underwater, the murkiness made it difficult for him to make out specific shapes. A small school of silvery fish swam past him, startling him for a moment and he held out his wand. He let out a sigh of relief that came out in large bubbles that rose up, blocking his view.
