The night was drawing in around Hogwarts Castle, Rowena was hurrying up the steps leading to the Front door, intent on not being late for the End of Term Feast. Just as she was about to enter the Great hall, the doors burst open. Godric and Salazar were rowing with each other. "NO MUDBLOOD WILL EVER BE ACCEPTED AT THIS SCHOOL NEXT YEAR! JUST LOOK WHAT THEY'VE DONE! POISONED THE MINDS OF OUR PUREBLOOD CHILDREN!" roared Salazar, a vein throbbing on his head.

"THEY WILL! WHAT IS WRONG WITH MUGGLE BORNS ANYWAY, THEY ARE GENIUNE, NICE PEOPLE, DON'T YOU DARE MAKE MY STUDENTS FEEL UNCOMFORTABLE!" argued Godric.

"IMPEDIMENTA!" screamed Salazar. He jumped the stairs two at a time, Godric advancing slower than a tortoise.

"Salazar!" shrieked Helga, who had just stumbled out of the hall, clutching her leg that was bleeding. It was too late Slytherin was already on the floor above.

"What has happened here?" asked Rowena, clearly outraged.

"It was Salazar! Two seventh years were snogging, a pureblood and a muggle born. He just went berserk! He stunned them both and when myself and Godric tried to restrain him he did this," Helga pointed at her leg. "And then went for Godric!"

"He's not going to get away with this!" fumed Rowena. She stormed up the stairs.

"No… Come back…" Helga called feebly before falling in a heap.

Salazar was sprinting through the corridors of the castle. He had to leave, but not without leaving something behind, something dark… He considered a Horcrux, but no, he had plenty of them hidden elsewhere. What would be one thing Godric couldn't stop or destroy? In his mind a plan began to form.

Rowena was hiding in the darkness watching as Salazar bent over something that couldn't be seen because Salazar was in the way. "Arbcrista, solena harones!" he hissed.

A higher pitched hissing replied, Rowena's heart was pounding, Salazar was hatching a Basilisk! She had to do something, she had a good idea what Salazar was going to do with the serpent and it wasn't good. She leaped out of her hiding place, keeping her eyes closed. "Avis! Oppugno!" she screamed.

Canaries appeared and zoomed straight at Salazar. He flicked his wand and the birds exploded into flame. "Petrificus Totalus!" shrieked Salazar.

He began to cackle insanely. "You thought you could stop me? With your books and theoretical magic? PATHETIC!"

Rowena was terrified. "You won't get away with this!"

"Oh, and you're going to stop me are you?" Salazar sneered.

"Please, don't kill me!" pleaded Rowena.

"What makes you think I'm going to kill you…? I'm going to do something much worse than that!" Salazar flicked his wand and Rowena found herself inside a giant ice-cube. "I presume you know what that is?" asked Salazar.

Rowena tried to move her mouth but it wouldn't budge. "Impervious Ice, there is no escape, no heat can melt it. Only the kiss from a virgin on a full moon will set you free!"

Rowena began to cry.

Salazar then placed Rowena in a secret chamber under the lake, protected by Inferi, Dementors and many other evil things. Salazar made an illusion of Rowena who acted as normal as ever. She even had children, relationships and illnesses.

1000 years later Sirius Black along with James Potter find this 'tomb' and with it unleash horrifying consequences.
