To change the future to better one

The four champions

Dark, autumnal clouds hang over the castle. With a massive thud, Moody drops a textbook onto Neville's desk, the same textbook on everybody's desk, the Dark Forces: A Guide to Self Protection. 

Mad eye: I see you all slogged down to flourish & blots like a good little students and brought the textbooks. Congratulations you won't need them. I am Alastor Moody, Ex-Auror ministry malcontent and your new Defence Against the Drak art teacher. I'm here. Dumbledore asked me, end of story. Goodbye. Any Questions?

Many Aurors and teachers share glances with one another while the golden group subtly looks at Barty, who is too busy trying to push regulas off his seat.

Mady eyes: When it comes to the Drak arts i believe in a practical approach you may wonder what i mean by that. I'll show you but first which of you can tell me

Moody took a spider specimen jar

Mad eye: How many Unforgivable curses are there?

Mi looked at Alastor smiling sweetly, which made him gulp

Andromeda said, " I'm sorry, what?"

Molly continued," I understand they need to know about them, but aren't they a bit too young?"

The students trade uneasy glances. Sahithi rubbed the cursed scar on her neck. Harry squeezed her hand, seeing that she just gave him a slight smile.

All now remembered that Sahithi has been under the crusio 

King and Kiara checked her neck to see there was a mark

The mikealsons, Silver Trio, and Maradures are furious seeing the mark

Hermione raises her hand tentatively. Harry and Ron are shown staring at the spider with scared faces as his real eye continues to stare at the spider. His moody blue eye rotates onto Hermione. 

Mad eye: I might've known to go on, granger

Hermione: There are three, sir

Madeye: And they're so named?

Hermione:  Because they're unforgivable the use of any of them

Mady eye: will earn you a one-way ticket to Azkaban, correct? Now, the ministry says you're too young to understand this curse. Do u say differently? You need to know what you're up against. You need to be prepared. You need to find another place to put your gum beside the underside of your desk, Mr.Finnegan.

The hall shouted at  the screen

Seamus blinks, caught in the act

Seamus: Blimey, the old codger, can see out of the back of his head

The hall chuckles slightly

Mad eye: And hear across classrooms, so which curse do we see first? Weasley

Ron: Y-yes?

Madeye: Give me a curse

Ron watches uneasily as Moody reaches and lets the spider run up his hand.

Molly, Arthur, and Prewett twins shake their head

Hoping Ron won't answer

Ron: Well, my dad once told me about one the Imperius curse

Madeye: I expect you, your father, would know that one. I gave the ministry a fair bit of grief some years ago. Perhaps this will show you why: Imperio!

The great hall flinch.

As Moody waves his wand, the spider leaps from his palm onto Parvati's shoulder. As she shrieks, moody flicks his wand, and the spider bounds from Seamus to Dean to Lavnerd on and on, the students howling with amusement as if finally landing on a horrified Ron Sahithi glares at Moody, who grins then summons the spider back, to his palm. Where he slowly circles his wand over it
