I am sorry this took so long, but I went to Wales for a week with a very mad set of people… Anyways, it's Quote Time!
'Put the wand down and step away from the hexes'
The soulful eyes of a certain Gryffindor boy were half closed with concentration as he read from a large book which he had found settled upon a table in the Common Room. Usually he was not one to pry, but this had interested him greatly. He was, after all, a 'Bookworm of the First Order' as Sirius so amusingly called him. Yes, this was none other than Remus J. Lupin.
Just as the quietest Marauder was reaching an interesting chapter containing spells to be cast over a large number of people at once, his peaceful surroundings were invaded by the chatter and noise of his two best friends. Shutting the book, Remus rolled his eyes. Typical!
"Moony!" James exclaimed in a cheery tone, flopping down upon the sofa right next to Remus.
"Remus, where've you been hiding? You missed two arguments involving Evans! You could have defended poor ickle Jamesy!" Sirius said in a mock serious tone.((no pun intended)) But the look of rage upon James' face proved too much and he laughed.
"Cheers Padfoot" James grumbled, obviously not in the best of moods when it came to thinking about his encounter with Lily. It had bothered him. He did not know why, but it had. Sure, he fancied her but… That should not have been enough to make her words sting the way they had done.
"Earth to James, come in James" Remus intoned, wafting one hand infront of the 'charming' Mr Potter's face. He got no response.
Remus and Sirius sighed simultaneously then grinned. They did that a lot, you see, and adored the eerie feeling it gave those that saw it happen.
So there they were, sat in the Common Room, blissfully unaware that three witches were currently out in the grounds of the school plotting revenge.
(Let's take a look outside….)
Smirking, Lily trailed her fingertips over the parchment on which the spell and all the preparations had been copied out. Well, she certainly would not be the one to heave that overly-large book around with them!
"This is going to be perfect" Kim giggled as she dug another piece of parchment out of the bag that was settled upon her knees. The three girls were sat under the shade of a large oak tree, each one with an eager look in her eyes.
"I might feel sorry for them y'know" Less found herself chuckling "If not for the fact that they deserve this"
The two other Gryffindor girls nodded, each with a smile upon their face. They were already half way through the necessary preparations, and not one of them desired to wait much longer.
Kim flattened the parchment out upon the ground and tapped it with her wand whilst speaking a quote that she knew and loved, being a fan of Muggle plays "If music be the food of love, play on"
At first nothing happened. Then the parchment began to glow a dull lilac with black lines twisting and turning upon the surface. After a moment, the glow vanished and the lines settled into words. These were the words of an incantation that had to be written then spoken to work. The True Voice Spell did, after all, require some use of the voice.
'For those that wish to speak their mind
The magic in music they must find
Twisting, turning, the notes in the air
Bending the rules to their whim and care
For seven suns and moons there may
Be songs around all night and day
These last lines seal the spell
Complete it, use its power well
For now it is done, it wont be long
Until your surroundings burst into song.'
Only one more thing was needed. And it was going to be Lily that got it. Why? Well, she was Slughorn's favorite pupil, after all. Indeed, it was something only found in a Potion Master's collection; a hair from the head of a Siren!
