It’s the battle of Hogwarts. You and Mattheo Riddle started dating a few months ago. The problem is, the Dark Lord (Voldemort) gave you an Ultimatum. Choose your sides. Either you join the death eaters, you will not be killed and can stay with Mattheo. Or you stay at the Order's side and die together with your "friends and family".
It is june 18th 1996, and Harry Potter had a nightmare about Sirius Black beeing in danger. And since Harry's predictions were true before, with Arthur Weasley. So a part of Dumbledore’s army, consisting out of Harry, Ron, Hermione, Ginny, Neville and Luna made their way to the Department of Mystery to save Sirius from danger. What they didn’t expect was, that this was all a well made trap by the death eaters to get the Prophecy out of Harry's possesion. Before the death eaters could harm any of the children, the Order of the Phoenix came to rescue. Thought, as history should know it, Sirius Black is supposed to die today.
