The Grey City has always been a place where it's better not to ask too many questions. Ever since superpowers were banned, everyone who still had them had either disappeared or learned to hide their abilities better than their own fear. Lena thought she was one of those ordinary, average teenagers who, by their existence, do not attract the attention of any monitoring system. Everything changed that August afternoon when, after an argument with her mother, she ran out of the house, wanting a break from the world.
