As he probed at the lock he realised there was a gap in the pattern, a blank area. He concentrated for a moment, forming a pattern to fill in the blank space. He got the pattern right, but not the shape. It didn’t fit and the pattern soon disintegrated. Ned repeated the process several times before getting both the pattern and the shape right. Nothing obvious changed, but Ned could feel the difference. The whole pattern of the lock had shifted slightly. Buoyed by his success Ned moved onto another lock. This one was trickier, the pattern was unlike anything he had created before. It took him several attempts to just match the pattern, then several more to get the shape right. Finally he did and the lock changed, the energy flows settled into a new pattern. Ned continued to work
