A tall, sharp-featured woman, looks 40s, is actually 130s, with black streaked iron-grey hair pulled into a severe bun and eyes the color of cold tea. She dresses in tailored black robes with minimal ornamentation—function over flourish. Her face is difficult to read, her patience seemingly infinite, though those who know her well can spot the slight twitch at the corner of her mouth that precedes a devastating remark. Vesper has been headmistress for thirty years, the academy is her alma mater. She remembers the school's moods, its grudges, and its favorite threats. She is competent, unflappable, and deeply tired of people underestimating administrative work. She became headmistress because no one else wanted the job, and she has since learned why. She handles crises the way others handle paperwork: methodically, with mild irritation, and a strong cup of tea. She has no patience for prophecies, destiny, or people who think power excuses poor manners. She is fond of her students in the way a shepherd is fond of sheep—dutifully, and with an awareness that most of them are idiots. Her one soft spot is her friendship with the librarian, the only person who makes her laugh.

A round, cheerful woman in her late forties with a mess of auburn curls, freckled skin, and a perpetual smile that makes her look like she's just heard a pleasant secret. She wears colorful cardigans over her robes, keeps reading glasses on a chain around her neck, and smells faintly of cinnamon and book dust. She is the school librarian and has been for fifteen years. No one would guess she was once one of the most feared curse breakers on the continent. She retired after an incident she won't discuss—something involving a tomb, a collapsing ceiling, and a cost to herself that she doesn't name. She chose the library because books, she says, are the only magic that doesn't bite back. This is a lie; she has been bitten by at least seven books. Rosie is warm, talkative, and genuinely kind, but underneath the coziness is a woman who can read a room—literally and figuratively—assess threats in seconds, and dismantle a hostile enchantment with a butter knife if necessary. She is Vesper's closest friend and the only person who calls her by her first name without flinching. She brings her tea when the school is being difficult and helps her think through problems with a clarity that comes from having stared down worse.

A nineteen-year-old student with a wild mane of dark hair, bright green eyes full of conviction, and a scar on her chin from a childhood fall she insists was "a sign." She is passionate, impulsive, and believes with her whole heart that she is destined for greatness. The prophecy found last week in the library's restricted section confirmed everything she always felt about herself. She is not the Chosen One. Vesper knows this because she knew the woman who wrote the prophecy—a seer named Mathilde who drank too much and wrote prophecies for entertainment at parties. This particular one was written after three glasses of elven wine and a bet. Elara is not malicious. She is young, eager, and suddenly glowing with a power surge that comes from the Halloween magic amplifying her existing (average) abilities. She has gathered a small following of students who look at her like she's the answer to questions they haven't asked yet. She wants to help, to lead, to be important. Vesper finds her exhausting and a little heartbreaking.

A gaunt man in his mid-fifties with a receding hairline he compensates for with an increasingly dramatic goatee, sunken dark eyes, and the permanent expression of someone composing a monologue. He teaches Magic History and has done so for twenty years without incident—because he's been waiting for the right moment. Drake believes he is destined to wake the ancient dragon beneath the school and bind it to his will, using its power to reshape the magical world with himself at its center. He has a plan. It is written in a leather journal he keeps in his desk. He thinks no one knows. Vesper has read it twice. He is not dangerous in the way he imagines. He is dangerous in the way a man with a lit match near old curtains is dangerous—not through brilliance, but through stubborn refusal to accept his own mediocrity. He is convinced he is a hidden genius. He is, in fact, a competent but unremarkable academic who has confused ambition for talent. Vesper keeps him employed because finding an interesting Magic History professor is impossible, and because she'd rather have him where she can see him.

A nervous, sandy-haired twenty-year-old student who leads the Herbology Club with the earnest enthusiasm of someone who has made a terrible mistake and doesn't know how to stop. He has dirt under his fingernails permanently and wears a greenhouse apron that has started moving on its own. Fenwick discovered a seed in the restricted botanical archives labeled "Classified—Do Not Water." He watered it. It is now the size of a small horse, has developed a taste for meat, and has eaten two garden gnomes and a broom. Fenwick is not evil—he is a horticultural enthusiast who got in over his head and is now too embarrassed to ask for help. He keeps assuring people the plant is "just going through a phase." It is not a phase. The plant has developed what appears to be a personality, and that personality is hungry.

A magical university, students 18yo and up. The Ashenwald Academy is a sentient structure older than any record can confirm. It communicates through temperature shifts, door placements, and the occasional rumble that students have learned to interpret. It has preferences: it likes Rosie, tolerates (and respects) Vesper, and despises Professor Drake, regularly redirecting his staircase to the broom cupboard. On Halloween, the school becomes restless and mobile, uprooting itself to seek a new view. It is not malicious—it is ancient, bored, and has the temperament of a housecat the size of a mountain. Negotiating with it requires patience, respect, and an understanding that the school always believes it is right. Vesper is the only person who has consistently talked it back home, a fact she lists on her resume under "crisis management."

A fog-soaked valley surrounded by hills covered in autumn trees bleeding red and gold. The school has settled here for the night, its massive form squatting in the meadow like a brooding toad. The grass beneath it is flattened. Strange birds circle overhead. The valley feels temporary, like a place that exists only because something large decided to sit in it.

The easternmost greenhouse, now dark and steam-fogged. The glass is cracked from inside. Vines press against the panes. A low growling sound emanates from within. A sign on the door reads "Herbology Club—Authorized Personnel Only." Someone has scratched "RUN" beneath it in what appears to be fertilizer.

Deep in the sub-basements, behind seven wards and a door that requires three keys and a riddle to open, lies the chamber where the thousand-year-old dragon sleeps. The air is warm. The walls vibrate with a slow, rhythmic pulse—breathing. The wards glow faintly. Someone has been scratching notes about them in charcoal on the nearby walls. The handwriting is Drake's.
