Flitwick did indeed take a while to 'lookup' the counter-charm which ould allow Umbridge to leave her office, the charm that Calliope cast was so effective that the room was not accessible to even the house elves who attempted to apparate into the room to deliver the woman food.

Hogwarts benefitted from a blissful Umbridge free week, and often many students gathered in the corridor outside her office to hear her shriek at them and threaten them with detention.

"But how do you know who we are Professor?" was the common response when Umbridge attempted this threat.

"I didn't know you had it in you," George patted Calliope on the back when he saw how effective her prank had been.

"I did!" said Fred proudly.

"I definitely did," Natalie grinned, "Callie may be quiet, but it's the quiet ones you've got to look out for. Everyone expects the loud ones to play jokes and pranks, but no one expects the quiet ones!"

Calliope simply gave the group a small satisfied smile.

"Guys!" Hermione Granger had approached the group, who were sat on a window seat during morning break, "I've been trying to find everyone, we figured we would make the most of Umbridge being locked in her office so we're having the first official meeting tonight!"

"You found a place?" Natalie asked.

"Yes, meet us on the Seventh Floor, opposite that tapestry of Barnabus the Barmy trying to teach ballet to those trolls, walk past the opposite wall three times thinking about a place for the meeting and a door should appear," Hermione said very quickly.

"Isn't that a broom cupboard?" Fred frowned, "we hid there from Flitch once."

"Believe me, you'll be surprised!" Hermione had a glint in her eye, "I've got to dash, I have to try and find everyone else! If you see anyone else let them know please!" Hermione bid them goodbye, before hurrying off down the corridor.

"I'm sure there's a broom cupboard opposite that tapestry," George frowned as he watched Hermione go.

"We definitely hid there once," Lee agreed.

Calliope shrugged, "Hogwarts is full of surprises."

"There is nothing on the Marauder's Map there," George had an expression as if he were trying to recall the exact likeness of an image he had studied for years.

"The Marauder's what?" Calliope asked, struck by the fact that George had mentioned the name that her father, Remus, Sirius, James Potter and Peter Pettigrew had used for themselves.

"The Marauder's Map," repeated Fred, "it's this map of Hogwarts that George and I found in Flitch's office, it shows all of Hogwarts, secret passages, people, ghosts," Fred listed, "If I could  meet just one of its creators I could die happy."

"You've met two of the Marauders," Calliope said, deep in thought about this map that seemed to have been created by her father and his friends.

"No way!" George scoffed, "Messers Moony, Beaky, Padfoot, Wormtail and Prongs are legends if I met one of them I'd know about it."

"Honestly, you've met two of them George, Fred has met three!"

"Go on then! Enlighten us! Who are they?" George asked, raising one eyebrow in doubt.

"Remus Lupin, Sirius Black, Peter Pettigrew, James Potter and my Papa, Isaac Doge," Calliope responded.

"You're yanking our wands!" George stared at her, "you mean to tell us that you're related to a Marauder!"

"Uh, yeah I suppose I am," Calliope frowned at the twins, this news seemed to be very important to them.

"This changes everything," Fred muttered, "this means that-Wait, does Harry know?"

"Yeah, I mean his Dad and godfather are Marauders too, he's known for more than a year!2

"And the git didn't tell us!" George's voice rose, "Freddie, I think it's time we had a word with the Chosen One."

"George, I was thinking the exact same thing."

Without another word to Calliope or Natalie, Fred and George got to their feet and stormed off down the corridor.

"Harry is going to get so pranked," Natalie said gleefully as she watched the twins go, "maybe they can use that Gorilla thing!"
