Hey,
Details are below
Luna ambled into the room of requirement with the other members and took a seat in a soft chair in the far corner of the room. Harry stood in front of the group and began talking about their exercise for the afternoon before splitting them up into groups.
It all went well enough at the beginning, getting everyone up to speed on their reflexes in casting and countering, but at some point Peeves had managed to find his way inside. The poltergeist was currently enjoying his discovery of the room by dumping an unknown grey sludge on anyone in his path. Luna hid under a table as she watched her classmates bolt each time Peeves made a dive.
"Take cover!" Harry's voice carried from the opposite wall and Luna couldn't help but wince when she heard the tell tale splatter of the sludge on the hardwood floor. At least this chaos managed to make the afternoon interesting...
