This is a fictitious article by the author. It is set in medieval England and the European continent. The story of Elizabeth I, known as the "Virgin Queen", was raised as a girl and became an outstanding female (?) Queen.
It's not history, but the general direction is to follow the official history, with a little bit of HP wizard background added, because the author has a deep love for fandom recently. But it's just a little bit, it won't affect the main drama~!
