stars are legend
A star body reflective of the cosmic sky, Changkyun's gift is a channel of the power of the stars. When there are none, such as in another world, his power reverts into something made of black matter with control over matter equal to that of a full black hole. By manipulating the power of the universe and the space between, Changkyun can manage to channel and manifest various gifts of the universe: from body draws to the representations of the constellations.
The most frequently used channel of the stars, Changkyun understand, control and create vehicles on a whim. The smaller the vehicle, the easier to make; larger vehicles might malfunction.
