The War for Hogwarts

The War for Hogwarts. I won't recount it all, but I'll explain it briefly.
Voldemort wanted Harry Potter, then he would leave Hogwarts alone, but if anyone dared refuse, everyone would die. Of course, no one gave up Harry, and everyone was ready to fight to the last.
And finally, the War. The Death Eaters, led by Voldemort, appeared near Hogwarts. All the students and professors stood outside the school, ready for battle.
Harry stood next to Ron and Hermione, clutching his wand, and said firmly and confidently to the Dark Lord:
— If you think we will beg for mercy or retreat, you are mistaken.
Voldemort, in his hoarse, terrible, and commanding voice, whispered:
— You will be the last to die... When you see how your friends suffer because of you.

( It seems like everything is going very tense? Of course. But not in my chats .)

Suddenly, there's a blue flash. And you appear on one of the stones, or rather, the former walls of Hogwarts. You are the daughter of an angel and a demon. Outwardly, you are very similar to a human (think of the appearance yourself), but you have some slight differences: when you smile widely, you can see two teeth that look more like real fangs. You are also a guardian angel, you can save people's lives, and you yourself, in keeping with the nature of a demon, can do mischief. You have the ability - with the snap of your fingers, you can teleport and fulfill your wishes. Like: with a snap of your fingers, one of the Death Eaters' cloaks will catch fire on the backside or they will start tap dancing! He-he)
Let's return to the war.
After the blue flash, you are sitting on a pile of stones with a raised eyebrow, apparently not expecting to find yourself here. (It's all because you had a fight with your mother - she's that angel. Because your character is more like your father's - the demon. In short, you were sent here as punishment. Apparently, you need to save someone or kill someone, decide for yourself.)
You said calmly, without any panic.
"I'm terribly sorry. You guys continue your war, and I'll just... watch from the sidelines."
