Aria POV
I sensed Voldermort arrived just now to apported to him.
As I saw him I put a barrier around us to keep the other Death Eaters from interfering.
Aria: Hello Tom.
He looked at me as my mask was covering my face.
Tom: You are no match for me little girl.
Aria: I surpassed you at the age of ten, your just in the way.
Tom: Avada Kadavra!
I shot Expelliarmus to clash with his death spell as I motioned with my hands to summoned Fiendfyre as it took the shape of a Dragon and roared.
Tom: You naive girl, no one can control Fiendfyre.
But then he was shocked as I commanded Fiendfyre effortlessly.
Tom: How?! Even I can't control it!?
Aria: Like I said, I surpassed you at the age of ten, now die and if you think I didn't know about your Horcruxes, I've already destroyed them.
Tom was shocked and petrified with fear.
Aria: That's what I wanted to see, the fear in your eyes, you are a shame on Merope Riddle's name.
Tom: How do you know of my mother's name?!
Aria: Well that's easy, I'm the Heir of Slytherin and Heir to House Gaunt, now begone.
As Fiendfyre rushed at too fast as he was screaming in pain of being burning alive as then he was silent as casted away the flames to see his remains in ashes.
I floated his wand to me as then the Death Eaters saw what happened and were shocked there leader could be defeated so easily.
I looked at them to smile at them as I apported back to the people as they saw me.
Villager: Is he gone?
Aria: Yes, Voldermort is dead once and for all, spread the word, The Heir of Slytherin has vanquished the Dark Lord once and for all.
As then I blasted the dark mark from the sky but to then summon lightning to strike down on the other death eaters as they ran.
The Villagers cheered as I smiled at them as they threw a feast for the whole village as they invited me.
Timeskip
The Daily Prophet published the Heir of Slytherin destroys the Dark Lord, everyone in school was shocked but the Pure Blood Families were angry at this.
I'm in Dumbledore's office with him and Professor McGonagall.
Dumbledore: Well I would say I'm surprised but I can't.
Minerva: Aria, I know you wanted to help but this was plain reckless.
Aria: I know Grandma, but I couldn't wait, he would caused more damage, enlisted more students to side when they graduated, it's bad of enough Hogwarts cultivated him here as that would already give us a bad reputation plus the families he would hurt or destroy.
I call her Grandma cause she acts like it to me.
Dumbledore: Quite right, and did you get all the Horcruxes?
Aria: Yes, he made four so I destroyed them before he could create another.
Minerva: Well now off to bed, tomorrow is the Pureblood family, you are required to be there as you are hosting it.
Aria: Right, I'll be off.
As I head out I smiled to know that I got rid of one challenge but the next is the Dark Wizards from around the around who are just as worst as Voldermort.
