Percy turned to Olivander and observed the torn robes and frail look to him. "Come, Mr. Olivander I have to see Horace Slughorn and then we can get you some food, bath and some new robes." Percy said and ushered the other man ahead of him.
Slughorn was at his desk in the classroom going over papers. "Mr. Weasley what can-" He stopped as he recognized Olivander. "Olivander my old friend! Mr. Weasley where did you find him?" Slughorn said waddling around the desk and coming forward offering his hand as Olivander took it.
"I'm afraid I've been a guest of the Dark Lord, Horace." Olivander said weakly.
"And I didn't find him. Peter Pettigrew brought him here per Harry's request. I can only assume this is why he released Peter a while back after Snape and Draco caught him." Percy said frowning.
"Yes, yes well I am glad your out of the mans clutches now Olivander." Slughorn said shuddering.
"As am I, I remember like it was yesterday when he came in for his wand. And then when Harry came to me a few years ago I had reason for concern for the boy. His wand was the mate of the one I sold to the Dark Lord many years ago." Olivander said. "He has a new one now. Voldemort I mean. I was forced to make it for him I'm afraid." He finished.
"But with a little surprise I hope." Percy said winking. "Right Mr. Olivander?"
"Are you barking mad young man? I am the greatest wand maker in the world and I did not get that way by selling faulty wands!" Olivander look scandalized.
Percy's heart sunk into his gut. "Ah yes. Well Horace I need you to let your friend know that the twins will be using their latest invention on the vampires across the wall. Maybe he should find another place until tonight so he'll be safe."
"Ah yes I'll go see him now. It was good to see you Olivander." He said getting up and waddling out of the room.
"Well Mr. Olivander this way." Percy said looking slightly guilty under the older mans scrutiny. He showed Mr. Olivander to a suite of rooms in the staff area and left him there to eat attended by one of the house elves and made his way back the astronomy tower. His father was standing there talking to Charlie when he returned.
"Percy I was just looking for you. I saw Charlie and he told me that the twins are planning to surprise the vampires? Is that right?" Arthur asked frowning. "How could you let your brothers try something like that Percy?"
"Dad if I don't they'll only do it on their own." Percy said looking his father straight in the eye. "Better to let them have permission on this. And as yet they have failed to disappoint."
His father sighed and looked back out at the giants and the vampires around the wall. "What about the giants?"
"Their our next target if we can get to them before Voldemort gets here." Charlie said.
"There they go." Arthur said as they saw the twins emerging from the castle with broomsticks in one hand and sacks in the other. They took flight after clearing the doorway and made a wide arc and circled back toward the wall. Riding along the castle side of the wall the vampires took in after them unable to cross to the other side but unwilling to stop the chase.
Then suddenly both of the twins threw something ahead of them but toward the other side of the wall before they veered off back toward the castle. The projectiles exploded into a great mist cloud and the vampires flying too fast to stop zoomed through. Suddenly screams and flashes of fire could be seen within the mist and nothing came out the other side. The mist slowly blew away on the wind and beneath where it was lay nothing but ashes on the ground. Two vampires that did not join in the chase stared at the spot for a few moments and then took flight in the opposite direction leaving the giants to their own fate.
