A/N: I don't own the any of the characters, they belong to JK Rowling. I also don't own the poem from which the italics are extracted. It was written by the Victorian Christina Rossetti.
Who sleep at ease amoung the trees,
Or wake to sing a cadenced hymn
With Cherubim and Seraphim.
Luna smiled to herself as she stood in the middle of Dumbledores 'return to Hogwarts' speech, humming softly she walked out of the Great Hall and opened the schools front doors, pushing the heavy wood with all her might until they opened wide, affording everyone within the Hall (for many of the students had crowded around the centre tables) a view of the front lawn. A few gasped at the unusual creatures that stood on the grass.
The Hall had fallen silent as the 5th year student made her passage into the rain, spinning quickly, her robes laid abandoned in the dry, her skirt lifting slightly as blonde hair flew out like a halo. She stopped suddenly, and bowed low to the creatures that only a few others could see.
"Excuse me a moment my friend." she said before running back inside, pausing by her robes to retrieve her wand and transfigure her rain soaked clothes into a bruised bronze evening gown, and over to Harry.
"Come dance Harry,It's so rare for Thestrals to dance; they only dance when the other animals awaken to sing with Angels. Please Harry, the Angels are singing for us to dance."
"You can't Harry! Not with Loony!"
"Why not Ron? What can it harm? It's just a dance in the rain."
"Harry, you need to pick someone to dance, from a different house to keep the magic growing." Harry transfigured his robes into a muggle tuxedo as he surveyed the room.
"Malfoy, I dare you."
"What!" the Slytherin prince spluttered.
"unless you're scared to dance with Thestrals in the rain, worried your make up will run?" Draco glared as he stood, quickly transfiguring hos robes into finer material, the Hogwarts crest replaced by the Malfoy family's in silver.
"Don't forget to pick from a different house Draco." Luna shouted as she dragged Harry out into the rain, his hand grasped tight and a laugh on his lips as he bowed to the Thestrals, he easily began dancing alone in the rain with Luna, as he spun and moved, the sound of Angels singing filled his ears. As each person passed on the magic and stepped outside into the thunderstorm to dance in transfigured robes, the Angels sang louder, the numbers of voices growing harmoniously.
For the first time in memory, the students and teachers of Hogwarts danced together in the rain. As the clouds stopped their downpour, the music faded until it was just the humming of a lone Ravenclaw in a muddy bronze dress.
"Did you like the music Harry?"
"Yeah, I did Luna, was it really Angels?"
"No, of course not, there's no such thing as Angels Harry."
"Then what were we dancing to?"
"Rain. It makes a beautiful hymn if you listen closely and choose to dance."
"You mean to say, you got the whole school to dance in the rain, to non-existent music, on the first night back."
"No. I didn't make anyone dance, same as I didn't make the Thestrals appear, they always come and listen to the sorting. I just decided to dance. I'm not very good at dancing normally, but anyone can spin and twirl in the rain."
