Hogwarts Legacy vs. the Books: The Complete Canon Audit

Hogwarts Legacy made a promise no Potter game had made before: not a retelling of Harry’s story, but a fully explorable Hogwarts set in 1890, a century before a certain scarred first-year sails across the lake. A blank century is a canon minefield. Invent too little and the game is a theme park; invent too much and book readers start writing letters in red ink.

So we did what any responsible examiner would do: replayed it with the books open on our lap and marked every major lore decision on the official O.W.L. grading scale — Outstanding, Exceeds Expectations, Acceptable, Poor, Dreadful, Troll. Wand out, quill inked. Let’s audit.

Outstanding: the things the game gets eerily right

The castle itself

The headline achievement, and it’s not close. The Great Hall’s ceiling does its weather impression, the staircases move with malicious timing, the kitchens are behind the right painting, and the dungeons feel properly colder than the towers. More impressively, the game honors geography the books only sketch: the boathouse steps, the covered bridge’s rickety authority, the way Hogsmeade sits a genuine walk away rather than a loading screen away. This is the Hogwarts that lived in the collective fandom head, load-bearing walls and all. Grade: O.

The common rooms

The books only ever show us two common rooms from the inside — Gryffindor’s, constantly, and Slytherin’s, once, during a certain polyjuiced espionage mission in Chamber of Secrets, where it’s described with greenish light filtering down because the room sits under the lake. The game nails that eerie subaqueous glow, giant squid silhouette and all. Hufflepuff’s sett — reachable through barrels near the kitchens, round doors, botanical coziness — matches the supplementary canon precisely, and Ravenclaw’s tower gets its airy blue-and-bronze library-in-the-sky treatment. For thousands of players, the game was their first time inside their own house’s room. It treated that moment with the reverence it deserved. Grade: O.

Phineas Nigellus Black, worst headmaster on record

Book readers know Phineas Nigellus mostly as the sardonic portrait in Dumbledore’s office and Grimmauld Place — Sirius’s great-great-grandfather, remembered as the least popular headmaster Hogwarts ever had. The game hands this man the actual headmastership during your school year, and the characterization is pitch-perfect: vain, indolent, allergic to students, delegating everything to the endlessly patient Professor Weasley. It’s a deep-cut casting choice that makes the timeline feel researched rather than decorated. Grade: O, with house points for nerve.

The Room of Requirement — and who knows about it

Making the Room of Requirement your home base sounds like fan service until you remember the books’ own rules: the Room appears to those in need, and — crucially — house-elves have always known about it. Dobby is the one who tells Harry it exists, calling it the Come-and-Go Room, and elves use it routinely. So a house-elf like Deek guiding a student to it isn’t a stretch; it’s an application of established elf lore that most fans had forgotten. This is the game’s canon craftsmanship at its best: what looks like invention is actually retrieval. Grade: O.

A decent Gaunt, who is still a Gaunt

Ominis Gaunt — blind, principled, quietly furious at his own family — initially reads like a contradiction of everything Half-Blood Prince tells us about the wizarding world’s most decayed pure-blood line. Then the game reveals he’s a Parselmouth, exactly as every Gaunt must be, and uses the gift he’s ashamed of as a literal key in the Slytherin-flavored questline. Heritage as burden rather than destiny is a very Potter theme (ask Sirius), and threading it through Voldemort’s own ancestral line without breaking the genealogy is genuinely deft. Grade: E, and only misses Outstanding because the family’s timeline is left prudently vague.

Peeves, restored to the castle

The films famously cut Peeves entirely — eight movies of Hogwarts without its resident poltergeist, a wound book readers never quite stopped mentioning. The game puts him back: cackling through corridors, ratting you out to prefects if he catches you sneaking, being precisely the chaotic nuisance the books describe. A century before Harry, this is exactly right — Peeves has haunted the castle since its founding, and a 1890s Hogwarts without him would have been the actual canon error. Restoring what an earlier adaptation deleted is the deepest form of fan service there is. Grade: O.

Exceeds Expectations: honest inventions, honestly walled off

Ancient magic

The game’s central mystery — a lost, wild form of magic only the protagonist can see — appears nowhere in the books. That’s precisely why it works. Rather than contradicting known magical theory, the writers invented a sealed branch: kept secret by its Keepers, spent by the story’s end, explaining neatly why nobody in 1991 has heard of it. Additive canon that cleans up after itself is the least a century-earlier story owes us, and it pays in full. Grade: E.

The goblin rebellion of 1890

Every student who ever dozed through Binns’s class knows goblin rebellions are a running feature of wizarding history. Ranrok’s uprising invents a new one in an open slot on the timeline, and — braver — gives the goblins an actual grievance rooted in wand prohibition and wizard condescension, which the books themselves establish through Griphook. It flirts with more moral complexity than it finally delivers, but the foundation is straight from canon. Grade: E.

The thestrals are earned

Here’s a rule the books guard jealously: thestrals are visible only to those who have watched someone die. It would have been so easy for an open-world game to ignore this — skeletal horses are excellent content — and hand you a thestral like any other mount. But look at the game’s opening hour: before you ever reach the castle, your journey is attacked and a man dies in front of you. Whether or not the writers ever say it aloud, your character qualifies. The dark rule is satisfied before the first thestral appears, quietly, in the story’s own arithmetic. That’s the kind of detail you only get from writers who fear their audience in the healthy way. Grade: E.

A fifth-year transfer student

No one transfers into Hogwarts in the books; the game knows this is strange and makes the strangeness the plot. Your late enrollment is treated in-world as unprecedented, tied directly to the ancient-magic mystery, with a professor assigned specifically to catch you up. Canon bent, but bent knowingly, with paperwork. Grade: E.

Acceptable: the stretches we’ll allow

• Ollivanders in Hogsmeade. Canon plants the venerable wandmaker firmly in Diagon Alley. A branch shop in Hogsmeade is retail expansion the books never mention — but never forbid. Fine. Wizards franchise. A.
• Merlin trials scattered across the Highlands. Merlin is canonically a Hogwarts alumnus of the distant past (house of Slytherin, say the trading cards every fan collected), so ancient puzzles in his name are plausible folklore. Slightly theme-park, forgivably so. A.
• Quidditch is cancelled this year. An injury, says the headmaster; a design decision, says everyone. But note the craft: rather than silently omitting the sport, the game writes its absence into the fiction and lets students complain about it, which is exactly what students would do. The books themselves cancelled Quidditch for the Triwizard year, so there’s even precedent. A, awarded with a knowing look.
• Beast-keeping in a magically expanded vivarium. A bag that’s bigger on the inside and a pocket nature reserve are both straightforward applications of extension charms canon has already blessed — a certain beaded handbag and a certain suitcase full of creatures walked so this vivarium could run. A.
• Demiguise statues that only wake at night. Borrowing the Demiguise — canon’s premier invisibility creature — for a moonlit collectathon is whimsical rather than doctrinal, and the creature’s lore (seeing what’s yet to come, hiding from what’s here now) makes it a rather elegant choice for statues that hold secrets. A.
• Choosing your own wand. Canon’s most famous retail rule says the wand chooses the wizard. The game’s Ollivanders visit runs the ceremony — and then quietly hands you a character-creator menu of woods, cores, and handle colors. The fiction says chosen; the interface says browsed. We understand why (nobody wants a randomized wand for a hundred hours), but let’s not pretend Garrick’s grandfather would approve. A, on a technicality.

Poor: where the seams show

Floo flames as open-air fast travel

In the books, the Floo Network connects fireplaces — it’s domestic infrastructure, regulated by the Ministry, and stepping into it means arriving in someone’s hearth, possibly the wrong one. The game scatters glowing green waypoints along country roads like magical bus stops. It’s the right aesthetic borrowed for the wrong mechanic, and every book reader feels the borrow. A carriage network, brooms-only travel, or an invented charm would all have been cleaner than overloading an established system. Grade: P.

A school trip to Azkaban

One questline can whisk a student to the wizarding world’s most feared prison, dementors and all, essentially as an errand. In the books, Azkaban is a place whose mere name makes adults flinch; Hagrid returns from a short stay visibly diminished. Treating it as a location you visit rather than a dread you carry flattens one of the series’ most carefully built horrors. Atmospherically the scene is appropriately grim — narratively, it’s far too easy to walk out of. Grade: P.

Troll: the one true canon break

Unforgivable Curses without unforgivable consequences

Here’s the books’ brightest legal line, delivered in a Goblet of Fire classroom: using any Unforgivable Curse on a human being earns a life sentence in Azkaban. Not a fine. Not detention. Life.

The game lets your fifteen-year-old protagonist learn all three from a classmate, cast them in open combat against human opponents, and face — nothing. No investigation, no expulsion, no mechanical cost, not so much as a stern letter. Companions briefly object, then adjust. The Sebastian Sallow questline actually wants to be a tragedy about exactly this — a good student rationalizing dark magic one emergency at a time, which is the most canonical arc imaginable — but the game can’t commit to consequences for the player that it applies to him, and the double standard guts its own morality play.

It is the single place where game design logic (players like unlocking powerful spells) flatly overrules world logic (this society imprisons you forever for these spells), and no amount of Highland scenery covers it. Grade: T, and we are being generous only because the Killing Curse at least still requires you to mean it.

One dishonourable mention rounds out this section: nobody writes home. You are an unprecedented transfer student at the center of a goblin war, and in a year of school you receive no letter from a worried guardian, send none, and apparently have no family the story can name. The books run on owl post — it’s the emotional plumbing of the whole series — and its total absence around the protagonist leaves them feeling less like a student and more like a very polite weapon the school found on the doorstep. Grade: P.

The examiner’s verdict

Tally the parchment and the pattern is unmistakable: Hogwarts Legacy is at its best when it retrieves — deep-cut headmasters, house-elf lore, common-room geography — and at its weakest when mechanics overrule the rulebook, as with fast travel and Unforgivables. Call the overall mark an Exceeds Expectations: a game made by people who demonstrably read the books, occasionally overruled by a design meeting that hadn’t.

More importantly for fans: its additive canon — the 1890s faculty, ancient magic, the Keepers — is built with enough care that you can accept it whole or ignore it whole, and the books close behind it either way. That’s how borrowed-world storytelling should be done.

Now, if the audit has you itching to re-enter the castle the original way, the definitive re-read order is right this way — and if someone in your life still needs the game itself (or the LEGO castle to put beside it), the gift guide has opinions. First, though: the Hat. It’s been patient with you. Go on.
