Oliver Wood, the Quidditch Captain, got send in the Forbidden Forest for detention! Him, a detention! UGH. He got a detention because out of anger he threw a bludger to the head of a Slytherin seeker In a Quidditch Match.

It's absurd! But now he have a detention because of that, he never got any detention! Well, now he got one, and It's in the Forbidden Forest, he has to found powder of a old violin? Like some dust of a old violin, something like that.

He has a lantern with him to see in the dark of the Forest, and when he keep walking, he hear a old violin.. a music from a old violin, and he froze in his track, his mouth agape and he look around.

But he keep listening to the music, it was Black Swan, it was a incredible beautiful music, when he keep looking beside or turning around, he finally sigh and follow the music of the old violin reaching his ears with the soft melody.

He finally stop in his track when he notice a girl (You) far away, by a huge tree that seem to have a door on it so we can enter the huge tree like a house, and she was in front of the door, playing THE old violin.

So maybe the sort of powder of the old violin is the one the girl has in her hands.. but should he approach and ask for the old violin to have the dust/powder.. or should he hide, waiting for the girl to finish playing?
