Harry Potter is in the Ministry in his Fifth Year - again.
Disillusion. Run. Prophecy room.
Yaxley. Peruvian Darkness Powder. Left pocket.
From their shouts, "he" had just disappeared - when he came out of the Veil - and caused his friends to panic.
Blame Ron, not me! Or praise him.
Fortunately, after Harry apparated just around the corner from the entrance, Yaxley was at the rear.
Once you understood human biology, silent killing with magic was far too easy.
Accio Yaxley.
Keeping the Disillusionment up, he silenced himself and dashed over in front of the Death Eaters.
Another spell dispersed the powder, most of it going towards Voldemort's people.
With a whispered spell he knocked his five friends to the floor. No time for a cushioning charm. If they broke things, he didn't care. No return fire would almost cut Hermione in half this time.
Dolokhov. Rookwood. Malfoy.
The big three were all killed twice to make sure.
He was only about 90% sure he'd eliminated Malfoy.
Fire at will.
He vaguely remembered MacNair being on the far right, so he was doubly lethal there. He moved as he fired, so no sound or angle would enable return fire to pinpoint him.
Whether he killed the remainder or not, their mission was over. And there was still no time. He dragged his friends swiftly using magic to levitate them, away from the fight behind a pillar. Just in case anyone was unconscious, he Rennervated them but silenced them.
"Keep quiet, be prepared to fight, I'll lift the silence but I have to leave and help others," he said, somewhat quietly.
Fortunately, his blind passage found the entrance and he only bumped into a couple of Death Eaters, neither of whom could reach up and grab him. He hated leaving any potential enemies behind, but again, there was no time.
As Fate, or Ron Weasley, would have it, he saw the start of the Black/Lestrange duel.
Bellatrix died instantly, and Sirius was Expulsoed forward to make sure.
He also did not fuck around the least little bit when Voldemort showed up. A spell sequence that mimicked the action of a rifle poured bullets into the Dark Lord. That worthy made the colossal mistake of immediately trying to possess Harry. Harry's mental barriers and force of will were plenty good enough to hold him at bay long enough for a combination of physical attacks and transfiguration inside Voldemort's reconstituted body to finish the fight.
He reduced Tom to ashes and vanished those. Dumbledore hadn't even had time to appear and banter with Voldemort.
Harry had long ago decided that if killing Tom's physical body gave you years of reprieve, that was good enough. It visibly killed morale in the portion of the Death Eaters that had split off to confront the Order.
And there was still no time.
The powder still made the corridor near the entrance to the Prophecy Room too dark to see. Speed might let him bull through.
As it fell out, only one Death Eater was left alive and conscious groping around, yelling to try to get one of the Ministry Five to squeak. They were keeping their heads, and he couldn't praise them enough for that.
His speed did spin him around, but he caught himself on his non-wand hand and continued to where he'd left his friends. The Death Eater was, indeed, knocked to the ground, and Harry cast several lethal spells in the general vicinity of where he thought he'd fallen.
"They're all settled," he stage-whispered. "Hermione?"
When he heard "I'm here, Harry!" he went over to her and gripped her arm. He estimated where her head was, and moved slowly towards her until he could feel the warmth of her cheek. Where her ear should be, he whispered, "Hermione, we need to talk privately, and soon."
Damned if I'll let Weasley as I know him have even one day of her precious life.
