Chapter 1: A Day of Very Low Probability

Summary

Harry Potter-Evans-Verres, a ten-year-old scientific rationalist adopted by Oxford biochemistry professor Michael Verres-Evans and his wife Petunia, receives a Hogwarts acceptance letter. Petunia reveals that her sister Lily was a witch who brewed a dangerous beauty potion that transformed Petunia from plain to beautiful. Michael dismisses magic as unscientific. Harry, experiencing a "peculiar certainty" that magic is real despite lacking evidence, writes a careful letter to Deputy Headmistress Minerva McGonagall requesting a demonstration. He tests the hypothesis by waving the letter in the garden and calling for an owl — and Mrs. Figg, a neighbor who knows about Hogwarts, intercepts it, promising to send someone. The chapter ends with Harry's stunned "What."

HPMOR-Specific Notes

Character Blocks (Veo-Ready)

Harry Potter-Evans-Verres

Harry Potter-Evans-Verres, a 10-year-old boy with messy black hair that sticks up at untidy angles. He has an unmarked face with no visible glasses or scar described in this chapter. He is small and slight for his age, wearing casual everyday clothes appropriate for a child in a comfortable academic household. He carries himself with surprising composure and confidence for his age, gesturing deliberately when he speaks, and his posture shifts between determined authority and childish vulnerability.

Petunia Evans-Verres

Petunia Evans-Verres, a woman in her late thirties with no specific hair or eye color described in this chapter. She is lithe and beautiful — formerly plain and ugly before drinking a magical beauty potion brewed by her sister Lily. She is dressed in casual domestic clothing appropriate for a comfortable home. Her face shifts between fear, defiance, and deep sadness. Tears gather in her eyes as she speaks about her past.

Michael Verres-Evans

Michael Verres-Evans, a tall man in his forties with no specific hair or eye color described in this chapter. He is dressed in academic-casual clothing suitable for a university professor at home. He stands tall and looks down at Harry dismissively. His posture is upright and confident, often with his nose in a book to assert intellectual dominance. He considers shouting uncivilised.

Arabella Figg

Arabella Figg, an old woman with grizzled grey hair escaping from a hairnet. She has a wrinkled face and a wrinkled arm visible when she reaches over the fence. She peers over the neighboring fence with a knowing, amused expression. She is not described as wearing any particular clothing beyond the hairnet.

Video Prompts (Single Strings, Veo-Ready)

Scene: ch01-revelation — Petunia Reveals Magic

Cinematic potential score: 6/10

A medium two-shot in a cramped living room with floor-to-ceiling bookcases covering every wall. Warm afternoon light filters through book-heaped windows. A yellowish parchment envelope with emerald-green ink sits on a cluttered table in the foreground. Petunia Evans-Verres, a woman in her late thirties with no specific hair or eye color described, lithe and beautiful, tears gathering in her eyes, stands defiantly facing Michael Verres-Evans, a tall man in his forties in academic-casual clothing, dismissive posture. Books frame them on all sides. Petunia gestures at herself, her voice breaking, as she tells the story of the beauty potion. Michael rolls his eyes and explains cold reading. The camera holds on Petunia's face as tears fall. Then Harry Potter-Evans-Verres, a 10-year-old boy with messy black hair that sticks up at untidy angles, small and slight, steps between them and speaks with surprising authority, proposing a scientific test. Camera pushes in on Harry's face as he delivers his argument. In a voice that is rapid and precise, with a British accent and an analytical tone, Harry says: If it's true, we can just get a Hogwarts professor here and see the magic for ourselves, and Dad will admit that it's true. And if not, then Mum will admit that it's false. That's what the experimental method is for, so that we don't have to resolve things just by arguing.

Scene: ch01-harry-letter — Harry Tests the Hypothesis

Cinematic potential score: 7/10

A wide shot of a suburban back garden with green lawn and afternoon daylight. Harry Potter-Evans-Verres, a 10-year-old boy with messy black hair that sticks up at untidy angles, small and slight for his age, wearing casual everyday clothes, stands alone holding a yellowish parchment envelope aloft toward the empty sky. His face shows determination mixed with deep embarrassment. The camera holds on him as he swallows his pride. In a voice that is strained and slightly tremulous, with a British accent and a tone of forced courage, Harry shouts: Letter for Hogwarts! Can I get an owl! Then a close-up over the neighboring fence: Arabella Figg, an old woman with grizzled grey hair escaping from a hairnet, peers down with a knowing, amused expression. The camera catches the shift on Harry's face from embarrassment to shock. In a voice that is bemused and kindly, with a British accent and a casual tone, Mrs. Figg says: Did you get your acceptance letter from Hogwarts?

Scene: ch01-mrs-figg — Mrs. Figg Takes the Letter

Cinematic potential score: 8/10

A close-up over a suburban fence in afternoon garden light. Arabella Figg, an old woman with grizzled grey hair escaping from a hairnet, wrinkled arm stretched out over the fence, opens an expectant hand. Harry Potter-Evans-Verres, a 10-year-old boy with messy black hair, small and slight, his face hot with shame, extends the yellowish parchment envelope toward her wrinkled hand. The envelope is yellowish parchment with emerald-green ink. The weight of destiny in a simple exchange. The camera holds on the hands meeting. In a voice that is warm and reassuring, with a British accent and a knowing tone, Mrs. Figg says: Just leave it to me, dear, and in a jiffy or two I'll have someone over. Her face disappears from over the fence. Long silence. Then a close-up of Harry's stunned face as he says, calmly and quietly: What.

Key Dialogue

"If it's true, we can just get a Hogwarts professor here and see the magic for ourselves, and Dad will admit that it's true. And if not, then Mum will admit that it's false. That's what the experimental method is for, so that we don't have to resolve things just by arguing." — Harry
"Oh, come now, Harry. Really, magic? I thought you'd know better than to take this seriously, son, even if you're only ten." — Michael
"My sister was a witch. Her husband was a wizard." — Petunia

Visual Notes

The Verres-Evans living room is defined by its books — every inch of wall space covered by bookcases, six shelves high, with science fiction paperbacks propped on tissue boxes to show the back layer. Books overflow onto tables, sofas, and pile under windows. This is the visual signature of the location: intellectual clutter, warmth, and the tension of a family that communicates through books rather than emotions.

No scar or glasses described in chapter 1. Harry's visual identity in HPMOR is built from scratch — messy black hair, slight build, surprising composure. The iconic scar and glasses are not mentioned until later chapters.

Mysteries Planted

  1. Why is Harry "utterly convinced" magic is real before seeing any evidence?
  2. Who sent the letter to the Verres-Evans address?
  3. What is Mrs. Figg's role — squib? Witch? Dumbledore's agent?
  4. What will the Hogwarts professor show when they arrive?
