Oh! Well. A turn is an ability. Three years ago a strange craft flew over London and gifted some people with turns. Mine is that I can see the flow of energy, know where it'll move, where it wants to move. Helps me visualize my inventions.
I've made shiners, little things that make bright lights to blind someone who might be trying to hurt you. A brightener, that helps amplify soundwaves so that it carries further. An automaton that drives the carriage, an autocarriage, all sorts of things, really.
