Department of Mysteries

"Are you sure that you need us to come along too?" Ashley asked Hermione. "Are you sure that 11 of us isn't too many?"
"Yeah, I mean, we're breaking into the Department of Mysteries. Surely you don't need us." James added.
"You never know what could happen. Maybe just guard the entrance. And send us a message if someone's coming." Hermione said.
Willow sighed.
"I have a bad feeling about this." Said Fawn. "Maybe we should go. We might prevent disaster."
"Usually when someone says they have a bad feeling about something, they mean that they shouldn't do it..." Said Ron
"I trust Fawn's judgement. Her predictions have never been wrong before." Said Max.
"Ginny, Luna and Neville are already going. You don't need us. I'm not going." Said Ashley.
"If you don't want to go, that's fine. I don't want anyone getting hurt." Harry said.
"Okay. Ash and I are staying here. But you will still have too many people." Said James.
"Do you even know who we are up against?" Ron asked. "The most dangerous wizard of all time."
"Ron's right." Said Max. "You wouldn't know the story, you don't know what we are up against."
"Max, I said that I don't want anyone getting hurt. I don't want to force anyone into doing something." Said Harry.
"Fawn, Max and I will join you. Ash and James can stay here." Willow decided.
Harry sighed. "Well. Come on them."
"How are we going to get there, Harry?" Asked Hermione.
"I have an idea." Smiled Luna.
---Time skip to the Battle at the Department of Mysteries---
"Harry, we need to get out of here!" Shouted Max over the flurry of spells flying as he grabbed Harry and Neville.
"They boy is right, Harry! You need to get out of here. Take the prophecy and go!" Sirius yelled and Max pulled Harry and Neville away.
Harry looked back to see Bellatrix about to fire a spell at Sirius.
Before Harry could yell out to Sirius, the spell was blocked.
"LUX IN TENEBRIS, VITA SUPER MORTEM! PROTEGE LUX, TENEBRAS PELLERE! LUMOS SOLEM!" Willow yelled. Each phrase made her shield stronger and the blinding light repelled the Death Eaters.
The members of the Order stopped, looking at the Death Eaters cowering from the light.
"WHAT ARE YOU WAITING FOR? GET OUT OF HERE!" Fawn yelled and dragged an exhausted Willow out of the room.
They collapsed beside Ron, who was recovering from the Thought attack.
"How... Did you do that?" Said Harry, breathlessly.
"Did what?" Asked Ginny
"That spell that stopped the Death Eaters. I've never heard that spell before." Said Sirius.
Willow rested her head against the wall behind her. "It's a... It's a long story..."
"Yes, Miss Jones is a very interesting and talented witch." They all looked to see Dumbledore standing behind them.
"But how did she do that spell? What was it?" Asked Hermione.
"It is a spell and a method that is not used by us. It's an older way of spellcasting. Come, we have a lot to discuss."

Yeah, well, sorry. It's been a while... The mini-series is coming to an end. So now I'm going to let you request scenarios if you want to and I'll write them up!
