It was the night James and Sirius had been planning for weeks, they were going to break into the Slytherin common room and cause havoc. And the best thing was no one would know it was them, except maybe Dumbledore who wouldn't tell anyway. The duo were getting ready in the dormitory when Remus entered and began to lecture them on the dangers of what they were doing. "If Dumbledore finds out you'll get expelled! You'll probably give the little ones heart attacks!" he lectured.
"Remus, can't you understand that nothing is going to stop us, so just shut and get out of the way!" James said.
"Whatever!" Remus replied angrily, the full moon was coming up, and that often made him moody.
James and Sirius began the long journey to the Slytherin common room.
They began the transformation just on the steps to the dungeons, James turning into a stag and Sirius into a large shaggy dog. They began bounding down the steps, they soon encountered a dead end. "Mudbloods and blood traitors will die!" said the stag.
The door slid open, revealing a large room lit with a eerie green light. The Slytherin Common Room. It was conveniently empty, the fire had burned low in the grate. "Come on, we need to get this over with." Sirius said.
Their plan was simple, as the common room was located under the lake, they would blast a small hole in the ceiling, then repair it. The whole common room would be flooded!
James aimed his wand carefully at the ceiling. "Confrin-" James began.
"What on earth are you doing?!" cried a small boy who had just emerged at the bottom of a stone staircase.
James jumped, his wand now pointed at a small patch of wall between two bookcases. "-go!"
Everything went cold. Sirius knew what it was before it flew out of the debris of the broken wall. And he was ready for it. "EXPECTO PATRONUM!" roared Sirius. A huge corporeal dog burst from his wand, then charged at the Dementor, which faded into nothing.
The little boy screamed and ran back to his dorm.
As the dust settled a huge chamber could be seen on the other side of the wall. James and Sirius nodded to each other and advanced cautiously into the chamber.
Thousands of Inferi lay dead on the hard marble floor. James and Sirius both went as white as snow, yet they still continued to advance. When they had reached the centre of the room they stood still. A wooden door was ahead.
"Help me… Please… I'm through the door right ahead… Help…" A melodic voice whispered echoing through the chamber.
Sirius charged forward and through the door. On the other side was Rowena, still in her ice-cube, tears frozen halfway down her face. "To free me I need a kiss from a virgin on the full moon. Now is the time!"
Sirius kissed the ice-cube which strangely was very hot on his lips. The ice suddenly transfigured itself into a pool of water and Rowena, for the first time in 1000 years was free. "Who are you?" asked Sirius.
"I am Rowena Ravenclaw, and incase you are wondering why I was in that ice-cube it was because of treachery by the slippery fool, Salazar." she said.
"Whoa! Hot stuff! Who's the babe?" asked James, walking into the chamber.
"Ravenclaw." answered Sirius.
"What?" James said incredulously.
"I am Rowena Ravenclaw, co-founder of Hogwarts School of Witchcraft and Wizardry, and discoverer of the 200 uses of Unicorn blood." Rowena explained, talking as if to an annoying toddler.
"Oh." said James.
BANG! The foundations of the school shook, as above the walls of the great school came crashing down.
