Minerva's Secret

It was a spring Saturday afternoon. Minerva was sitting in the staffroom reading The Daily Prophet. Minerva was the Transfiguration teacher at Hogwarts, Albus, the old transfiguration teacher, was promoted to Headmaster.

She noticed the new Divination teacher enter. She looked like a nervous wreck.

Her name was Sybill Treawlney. Sybill walked over to Minerva and sat beside her.

There was no-one else in the staffroom. Sybill began speaking and Minerva turned to face her.

"Two squibs, children of Minerva McGonagall" Sybill wiped her eyes.

"Sorry dear. Did you say something?"

Minerva stood up and walked to her office.

"How does she know about my children?" Minerva thinks.

Minerva had recently got married to an Waylon McGonagall. But he died shortly after their marriage. He left Minerva pregnant, with twins.

"Could Sybill really have predicted that my children would be squibs?"

For a few months Minerva just placed the thought into the back of her head. But then she gave birth to her children. In her London home. Not a sole knew about them.

She couldn't take the risk of having Squib children. So she gave the children, both boys, to her two closest Muggle families.

The eldest, Reginald, went to Mary and Arnold Granger. The second, Lionel, went to Peter and Annette Evans.

For years Minerva watched both families grow. Annette and Peter died when Lionel was 22 and he had started a family of his own. Mary and Arnold died when Reginald was 30. And the saw their grandchild.

Reginald married a lovely muggle called Kathleen. The had a son, called Andrew.

Lionel married Melissa and they had two daughters, Lily and Petunia. Minerva was surprised to learn that, Lily, had gained magical abilities. She watched as Petunia grew to hate Lily. When Lily came to Hogwarts, Minerva was glad that she was placed into Gryffindor.

Minerva watched Andrew and Petunia, but neither showed signs of magical ability.

Petunia married and oaf of a man, Vernon Dursley. They had a son, Dudley. Petunia did not want Dudley to develop magical abilties.

Andrew married a Gloria and they had two children. Arcturus and Hermione. Who both  devoleped magical abilities.

Lily married James Potter, a fellow Wizard whom she met at Hogwarts. They had one child, Harry. But they were brutally murdered by Lord Voldemort. Lily, used old magic that she studied at Hogwarts, to protect Harry. Harry survived and Minerva was relieved.

Harry was sent to live with, Petunia, Vernon and Dudley. Harry was magical, but Vernon and Petunia were against magic.

As time went on, Harry was taken from Petunia and Vernon, to attend Hogwarts.

Harry was in Hermione (they share the same great grandmother) year. And Arcturus was 4 years older than them.

Minerva watched these three closely. She watched Harry and Hermione get into trouble, and she watched Arcturus study bad magic.

When the second wizarding war came, Arcturus went to work for Voldemort. But as a spy. He knew Voldemort would eventually kill him, so murdered Pandora Lovegood to make it look like she killed herself.

By doing this, he split his soul, creating a horcrux. The Horcrux was a book, of advanced magic. He hid it a pocket in front of his heart.

When the battle was taking place. He saw Minerva trapped under fallen rubble, her wand broken.

"Take this" She said, tearing up.

Arcturus took the tear and went up to the pensieve in the Headmaster's office.

Arcturus saw Minerva's memory of giving away her children, the prophecy and also him being her Greatgrandson.

He raced back down and physically moved the rubble, dodging attacks from death eaters.

Minerva stood beside Arcturus and they dueled to death eaters. Arcturus had killed the death eater he was battling. But then a Death Eater shot 'Advada Kedava' at Minerva. So Arcturus dived in front of her, taking the spell.

"NO!" Minerva cried. She killed both death eaters. And then kneeled by her Great Grandson.

"You saved my life twice" she whispered.

"I know!" He said, getting up.

"How?" She asked.

"Horcrux" he said. He pulled the destroyed book of advanced magic out of his prophet.

Just as he did this Voldemort apparated into front of them. He disarmed Minerva and cast pointed his wand at Arcturus.

"You betrayed me. Do you know what I do to people who betray me?" He asks

"ADVADA KEDAVA!" He yells, killing Acrturus. Minerva fetched her wand and was about to duel Voldemort when he disapperated away.

Minerva lifted Arcturus's body inside. And laid him onto the floor.

Voldemort spoke and called back his followers.

Hermione, Ron and Harry walked into the great hall. Harry and Ron went over to the Weasley's who had lost a child. Hermione however walked over to Arcturus.

Minerva decided not to share the same information with Hermione that she did with Arcturus.

Minerva walked from the Great Hall and up to the pensieve were she cleared it. And she also altered her memory.

Sybill walked into the office.

"They will acheive great things. Descendants of Minerva" Sybill rubbed her eyes.

"Sorry, did you say something dear?" Sybill asked.

"Nothing" Minerva replied.

Sybill exited the office.

After the war was won, Minerva became Headmistress.  In a few years, the final children of hers, that she would be alive to see, attened to Hogwarts.

James Sirius Potter, Rose Weasley, Albus Severus Potter, Hugo Weasley and Lily Luna Potter.

Hermione had married Ron Weasley and Harry had married Ron's sister, Ginerva Weasley.

There was no longer Granger or Evans families. But now, a Weasley and Potter families.

For the rest of her long life, Minerva never regretted the decison of giving her kids away. Because if she did not, she would have changed the course of history, and Lord Voldemort would still be at large.
