Rose leaped in her clothes and got out of her room. Far away from her, were sounds of a battle enraging. She dashed her way through the deserted corridor. Streaks of moonlight flooded in through windows, illuminating her path. She just reached Gregory's statue, when she saw a shadow moving in light a little ahead.
She stopped, when something huge pushed through the castle wall. She looked away, shielding her eyes reflectively. After a moment, she turned her head. Among the flying dust and collapsing part of wall, there was a huge hairy leg.
A big spider raised itself to its full height, looking down at the human. Rose, took a step back, lifting both her hands at the beast. "Crucio!" she shouted.
The spider started shrilling as if someone was ripping it apart. It dropped onto the floor, moving its limbs fervently, trying to escape the torture. Soon, it stopped moving. "Sorry, Hagrid." The witch mumbled.
She quickly went down to the Great Hall. Around her, students and teachers fought Death Eaters alike. There were bursts of red and green sparks flying. She took her chance to take down the one coming in from the Entrance Hall.
She stopped around four to five enemy when she heard a girl scream. Turning towards the sound, she saw a Hufflepuff girl falling dead as her opponent let out a cold laugh.
Anger infuriated Rose. She immediately casted the 'Killing Spell' on the Death Eater. As soon as he was killed by the spell, Rose turned around and stupefied each and every enemy around her. Anyone who was able to see her assumed that she was trying to dance like a swan.
When all the Death Eaters were down, she heard screams and a loud explosion. It came from the entrance of the castle.
Rose ran towards it, stumbling over a bit fallen rubble but quickly regaining to reach the Entrance Hall.
Hundreds of Dementors were flying towards the castle. A few patronus whizzed over her head but neither stopped the spirits. "EXPECTO PATRONUS!" she screamed, shooting a silver light out of her fingers.
The light took shape of a doe and scattered the cluster of dementors. Just when she thought everything was under control, a giant came around the corner.
It swung its club and broken down a part of wall. More dust rose in air as a few magical suits of armors and a teacher rushed to stop it. "Stupefy!" Rose swung her arm up in air and the beast fell straight on its face, shaking the floor of castle.
She took a sigh of relief and backed against the nearest part of wall. The battle did not cease yet, more and more of enemies were pouring into castle, no matter how many ever she stopped or killed.
Rose was thinking all this when there was ground rumbling explosion, very close to her. She snapped her head up to see something falling towards her. Too shocked to move, she raised her arm up to cast a shield but it was too late.
About a ton of masonry fell onto her.
