The Floating World

There is a world, where everyone lives in the sky. Long ago, people came together and build sky cities to escape the monsters on the ground. Meet Lucian and his twin sister Aileen, who lost their mother a few years ago and are now living as broke nobles. Not only are they orphans now, but what's more, Lucian gets bullied, because he has, contrary to his sister, almost no talent in magic. Will he keep living this poor life and be carried by his genius sister or is Lucian going to show the world that he can't be underestimated?
