London in a downpour had its own particular heaviness — water everywhere, the smell of wet stone, the city going soft-edged and grey. Muggles moved through it as they always did: umbrellas up, collars turned, eyes on the pavement, the ordinary world running precisely on schedule.
Not one of them looked at the shop windows.
The windows along the edges of the park reflected the rain and the street and the blurred shapes of buildings — and, if you were looking at the right angle with the right kind of eyes, the slow movement of dark figures slipping through, absorbed into the reflection, gone.
There were hundreds of them.
Kevin arrived at the park at speed, the group at his back, and found it entirely empty.
"Draco," Harry said, scanning the open space, "where exactly—"
"It was supposed to be here."
Kevin had already stopped at the park's edge. His attention had moved to a shop window about thirty metres out, its glass silver with reflected rain. He watched it for a moment.
There.
He looked at the group. "Stay here. Set perimeters if you can. Something's going on in the Mirror World."
Hermione caught his arm. "Kevin—"
"I'll be fine. Aurors are on the way. Don't let anyone through those windows who doesn't want to be stopped." He held her gaze for one second. Then he stepped through.
The Mirror World hit him with its characteristic wrongness.
London, but stripped of everything alive. No pigeons. No dogs. No distant sound of traffic. The rain was there — frozen in place, hanging in mid-air, millions of drops suspended between sky and pavement like a shattered clock. The fog remained but the movement was gone from it.
And in the centre of the park, around a flat stone platform, hundreds of wizards stood packed together in complete silence.
Kevin recognised the faces. Death Eaters. Pure-blood families. A scattering of Ministry officials who were going to have an uncomfortable morning when the Aurors arrived. A full cross-section of every faction that had ever, for varying reasons, thought Voldemort might be right about something.
On the platform: Grindelwald.
He stood with his hands at his back and his chin lifted slightly — that particular angle that suggested he was looking down at the world not out of arrogance but out of simple height, the natural posture of a man who had always stood slightly above the crowd and had stopped noticing it.
Then he held out one hand, and the rain stopped.
Not just slowed. Stopped. Every suspended drop simply ceased to fall. The air went perfectly still. Somewhere, distantly, Kevin was aware that this was extraordinary even by the standards of the last fifteen minutes.
"I expect most of you know why you're here," Grindelwald said.
His voice carried without amplification — not loud, but present everywhere at once, the way that certain voices occupy rooms without effort. The quality of a man who has spoken to large crowds for a long time and has learnt precisely how much volume he actually needs.
"Some of you remember me." He moved unhurriedly along the platform. "Fifty years ago, I told you that the Muggle world would tear itself apart over its own greed. I told you the blast would reach us."
"It did."
"And why?"
He stopped. Looked down at them.
"Because I failed."
He said it without drama. A fact. He had tried to rally wizards to rise above the Statute of Secrecy, to separate openly, to take their place above the hidden world — and he had failed. That failure had let the war happen. He wore it plainly.
"Now," he continued, after a pause, "I'm glad it happened that way."
The shift in the crowd was visible — a slight unsettling, people recalibrating.
"If we had gone to war with Muggles at that moment — with their weapons, their numbers, their industrialised violence — the first targets would not have been each other. They would have been us. The visible, unusual, undeserving."
He paused.
"Because that's what Muggles do. It is in their nature. Greedy. Envious. Afraid of what they can't possess. If they cannot have something, they destroy it. If they cannot understand it, they burn it." His voice was even. Almost compassionate. A grandfather explaining a hard truth rather than a tyrant delivering a decree. "We are few. We are remarkable. And remarkable things draw the destruction of those who cannot be remarkable themselves."
The crowd listened. Even the ones who had come to see who had called this meeting, who had not yet decided what they thought — they were listening.
Kevin listened too, from the edge of the assembly, taking it in.
Grindelwald was good. He was very good. The self-criticism, the acknowledged failure, the positioning of Muggles as a structural problem rather than an enemy to hate — it was more sophisticated than Voldemort's blunt dominance politics. More durable.
And underneath it all, coiled in the careful phrasing, the slow seeding of contempt: Muggles will always try to take what you have. The only answer is distance.
"So—" Grindelwald's voice rose, not to a shout but to a resonance — "if you truly care about your families. About the world your children inherit. Do not waste your blood in a war you've already won the right to avoid."
"Rule them? You've already lost something precious in that word." He looked out across them. "War ends. But the world it leaves behind — Muggles and wizards side by side, everything exposed — is the world where your children are slowly, generation by generation, dissolved."
"The answer is not domination. The answer is separation. Full. Permanent. Final."
The noise in the crowd swelled — not agreement exactly, not yet, but the sound of a large group of people encountering a compelling argument for the first time and finding it more persuasive than they'd expected.
Kevin was already thinking three steps ahead.
He looked at the blue flames rising slowly around the platform's edges.
Right, he thought. Time to have that conversation.
"Grindelwald!"
His voice cut across the noise of the crowd without difficulty. Several hundred heads turned.
"I'd like to talk!"
The blue fire rose.
This story don't stop here, y'all. It never did, not once. More chapters breathing and waiting right beyond this page like a river that just keeps on running. Don't you leave curiosity unanswered, folks. That ain't right.
