I don't own any part of the Devil Wears Prada or Harry Potter but I love both worlds and Miranda would make a hell of a witch.
1.
Andy Sachs ran. She was being chased by horrid men who would torture her to death if they caught her. She did not want to die but she could not live with what was coming if she did nothing to stop it. He was hell-bent on killing someone and the glass ball in her hand would mean the death of an innocent family. So she ran.
She tripped, landed hard, and the glass ball flew from her hands. She hoped to see it shatter into pieces before she remembered the unbreakable charm used on all the items housed in the Department of Mysteries.
"Crucio," she heard a male voice say just before her world exploded in pain.
It took her overworked mind moments to realize that the loud screaming was coming from her own mouth.
She found herself pulled into a tight ball on the floor after the spell released her. She looked up at masked men who were all pointing their wands at her. Then one stepped forward pointing his wand and began to speak, "Avada,"
Before he could complete the spell he was hit by a strong spell that threw him violently backward casing the unconscious man to collide with one of his fellow Death Eaters.
The room then exploded into chaos. She looked up to see Miranda Priestly resplendent in white robes casting spells faster than she thought was possible. The Death Eaters scattered but quickly began to organize a competent counter attack. Andy retrieved her wand and was soon standing next to Miranda sending spells towards the crouching men.
They had just about driven the men into retreat when the air in the building suddenly changed. Andy shivered as the temperature seemed to drop precipitously. In moments ropes came from every direction binding Andy and Miranda tightly together. Their wands were taken from them as the Dark Lord approached.
"You are a brave girl to attempt to keep this from me," he said holding up the prophecy.
"You won't win," Andy said with a bravado she did not really feel but if she was about to die she would do it on her own terms.
"Brave, but stupid," he said.
"Crucio," he said barely above a whisper.
Andy shrieked again but instantly felt the pain lessen as Miranda squeezed her hand halving her burden in the process.
He released the spell before turning to the other bound woman.
"And you Miranda, I would have thought you to clever to be caught out like this."
"You being the brightest witch of your age and all," he continued with a sneering laugh.
"It's a shame really, with your heritage from such an ancient and powerful wizarding family that you didn't accept my invitation," he said.
"No matter that is water under the bridge now."
He held up his wand but instead of a killing curse he said, "Stupefy."
AN: This is the first chapter of a long piece. As you can guess this is very AU with a blend of HP and DWP characters with only a few cannon relationships in the story.
