Nearly everybody knew what had happened to Jamison, yet it was merely brushed aside since he was the only one, and no one thought it was a major occurrence.
The nurse and headmistress assumed it was just a cold or maybe lack of food or sleep, though since then the boy's magic didn't feel the same, nothing was exactly wrong with it, he just felt weak every time he casted a spell.

It was nearing Halloween night, students were of course excited, some decorating the halls, some carving pumpkins and others even making masks or cloaks. Essays and assignments were handed in today despite the little accident with Jamison.

It was also announced that after Halloween the first quidditch match of the year will take place, training has now gotten a lot more harsh and strict, the team are expected to be at every practise lesson there is. The first match of the year will be Gryffindor versus Hufflepuff.

But the morning of Halloween was unusual for some muggle Hating students, because when they woke up they had an odd green stamp sealed scroll.
And when opened it required them to meet in a strange room that none of them had even heard nor seen of, yet the map gave perfect instructions to...
The room of Requirement.

((The stamp is important it's a clue, well kinda~
Also some of traitors will be Pmed, not all of them just yet))
