2 May 1998 - the day that lies in infamy as the day that Voldemort and the Death Eaters won the Battle of Hogwarts. Before Harry Potter could reach the diadem, before the fighting could truly begin, Death Eaters stormed the castle and it was over before it had begun. Finally, with the Boy Who Lived in his hands, Voldemort was free to do as he pleased with the Wizarding World.
Those who were present at the battle, as well as all Muggleborns and those who are loyal to Harry Potter and the Order of the Phoenix, were rounded up. Hogsmeade was transformed into a concentration camp, and all of those who had been captured were imprisoned.
Witches and wizards from all walk of life now live together, scattered throughout numbered buildings in the town. They have duties they must perform, chores that need attending, and what little freedom they do have is carefully watched by the Death Eaters who rule the town. If anyone is caught breaking the rules, they are punished - and those who declare loyalty to Voldemort and the Death Eaters are rewarded. Life is no longer a right; it is a privilege.
All the while, the imprisoned Order of the Phoenix will do what it must in order to escape. But with little privacy, alert guards, and no magic at their disposal, all they can do is stay together and do whatever it takes to survive.
