I wouldn't call us fascists. More like highly selective.
Welcome to New Europe, run by the European Alliance. A mirror image of the world from which it was based, it is run strictly by Gellert Grindelwald and his Hallowed, the soldiers whom served him loyally in life. Taking the best, the brightest, and the most valuable from the wizarding world, they bring them to the New Society to begin again. With death impossible except by the will of the Leader, there is no escape from his grasp. All actions are closely monitored, all movements followed by soldiers who are determined to keep peace and preserve the sanctity of this place.
In a world where your ability to enter a bar is determined by blood status, all spells with wands are monitored, and where all people with creature blood must be owned by a master, there is no escaping the harsh reality. Freedom must be bought or sold with your soul, or by turning on the people you love. Arriving in the world at any age, in a realm controlled by a madman, midnight raids are common, forms of slavery are legal, and disappearances happen regularly. Insurgents are made into public examples, and the only freedom one possesses is that which is gained by absolute submission.
