Fourth Wing Trivia Cram Sheet

Three books, roughly 2,400 pages, boiled down to what a trivia host is actually going to ask. Skim it on the drive over — there's a 32-question self-quiz at the bottom.

Full spoilers

Everything below is spoiled through Onyx Storm, including the last page. That's the point — but warn anyone still reading before you send this.

The 80/20 hack

The shortest path through all three books. If you only give this page five minutes, give it these.

One picture

The whole series, illustrated

Illustrated cram sheet: Violet with Tairn and Andarna, Xaden with Sgaeyl, the Tairn–Sgaeyl mated pair, her lightning and dream-walking signets, riders versus venin, the 107 marked ones, and the four venin ranks from initiate to maven.

Tap for full size. One caveat worth knowing before you memorise anything off it: the artwork is beautiful but the lettering is garbled in places — it calls Tairn "Tatm", spells his breed "Morningstartall", and writes "helic" where it means relic. Picture-generators can't spell. The pictures are right; trust the tables on this page for the words.

Start here

If you only remember five things

These five get you through most of a trivia round on their own.

  1. Violet Sorrengail is the narrator — a small, chronically ill 20-year-old raised to be a scribe, whose general mother forced her into the dragon-riding track instead.
  2. She bonds two dragons, which nobody does: Tairn, a huge black morningstartail, and Andarna, a golden feathertail hatchling. Her power is lightning.
  3. The love interest is Xaden Riorson — shadow-wielder, son of the executed rebellion leader, and by the end, the very thing they've spent three books fighting.
  4. The real enemy is the venin: people who pull magic straight out of the earth, killing the land to do it. Their army is the wyvern. Navarre has hidden their existence for centuries.
  5. Onyx Storm ends with Violet waking up married to Xaden and missing twelve hours, holding a note that reads: "Don't look for me. It's yours now."
Setting

The world in ninety seconds

Navarre is Violet's kingdom — walled off behind magical wards. It has dragons. Its neighbor and enemy, Poromiel, has gryphons, and gryphon riders wield weaker magic because gryphons channel less power. The two have been at war so long it's just background noise.

Basgiath War College is where the first book happens. Four tracks, called quadrants: Riders, Scribes, Healers, Infantry. Violet was raised for Scribes. Her mother put her in Riders, where the death rate is not a figure of speech.

Terms the host will use

Worth knowing cold

The marked ones. When the Tyrrish rebellion was crushed, its officers were publicly executed and their children were marked — a shimmering rebellion relic twisting up from the wrist. There are 107 of them. They were fostered by loyal families and are all required to enter the Riders Quadrant.

The mark's real function is the good trivia: it was made by Codagh, General Melgren's dragon, and when three or more marked ones are together, Melgren can't see the outcome of what they do. That's why gatherings of three or more are forbidden — and why the rebellion can operate at all. Named marked ones: Xaden, Liam, Garrick, Bodhi, Imogen.

Roster

Who's who

In rough order of how likely a question is to land on them.

NameDragonPowerWhere they stand
Violet Sorrengail Tairn + Andarna Lightningplus dream-walking, book 3 Narrator. Trained as a scribe, forced into Riders. Joints dislocate easily — she wins by being smarter and better armed.
Xaden Riorson Sgaeyl Shadowsand secretly a mind-reader Son of Fen Riorson, the executed rebellion leader. Duke of Tyrrendor. Turns venin at the end of book 3 and vanishes.
Lilith Sorrengail Aimsir Storms Violet's mother and a general — the reason Violet is in Riders at all. Gives her life to power the wardstone at the end of book 2.
Mira Sorrengail Teine Manifests wards Violet's big sister, a rider. Held hostage as bait in book 3.
Brennan Sorrengail Mender (healing) Violet's brother. Presumed dead six years; the last-page reveal of book 1 is that he's alive and running the rebellion in Aretia.
Rhiannon Matthias Feirge Summoning Violet's best friend. Rises to wingleader. The steady one.
Dain Aetos Cath Reads recent memories by touch Childhood best friend and squad leader. Uses his power on Violet without asking, which is why readers can't stand him.
Liam Mairi Deigh Farsight Assigned to protect Violet, becomes her friend. Dies at Resson in book 1 when Deigh is killed — a rider dies with their dragon.
Sloane Mairi Siphonchannels others' power Liam's younger sister. Her siphon is how Lilith reaches the wardstone in book 2.
Ridoc Gamlyn Aotrom Ice Squad comic relief, and consistently braver than he lets on.
Sawyer Henrick Sliseag Metallurgymanipulates metal Squadmate. Loses a leg in book 2.
Imogen Cardulo Wipes recent memories Pink-haired, marked, prickly. Her power is the mechanism behind the final page of book 3.
Garrick Tavis Chradh Xaden's closest friend, and one of the marked ones. Missing at the end of book 3.
Bodhi Durran Xaden's cousin. Also marked.
Jack Barlowe Baide Book 1's bully. Violet kills him with lightning — then he returns in book 2 as venin and shatters the wardstone.
Aaric Graycastle Molvic A cadet under a false surname. Actually Prince Camlaen Aaric Tauri, the king's third son, hiding in plain sight.
Jesinia Neilwart Scribe, Violet's deaf friend, and the one who works out that the wards need seven dragon breeds, not six.
Quinn Hollis Astral projection Squadmate. Killed by a venin at the battle of Draithus in book 3.
Cat Cordella Gryphon rider From Poromiel, and Xaden's former betrothed. Exists to make things awkward.
General Melgren Codagh Sees battle outcomes Navarre's commanding general. Can predict any battle's result — which is why the rebels stay under his radar using the marked ones.
Major Varrish Book 2's on-campus sadist. Tortures Violet during interrogation.
Commandant Panchek Revealed in book 3 as the traitor inside Basgiath, tied to a venin sage named Berwyn.
Bloodlines

The two houses

The entire series runs on one fact: Violet's mother executed Xaden's father. Everything else — the distrust, the rebellion, the secret wedding — hangs off that. Here it is in one picture.

crushed his rebellion · had him executed Lilith Sorrengail General, Basgiath storm wielder · dragon Aimsir Asher Sorrengail Lieutenant Colonel, a scribe died of grief before book 1 Fen Riorson Duke of Tyrrendor led the Tyrrish rebellion Talia Riorson Xaden's mother Brennan mender · presumed dead for six years Mira rider · manifests wards · dragon Teine Violet narrator · lightning and dream-walking Xaden shadows · turns venin Duke of Tyrrendor Bodhi Xaden's cousin married in secret · Onyx Storm she has no memory of it bonded bonded Tairn black morningstartail Sgaeyl navy daggertail mated pair — so the riders can't stay apart dead before the end of Onyx Storm. Violet also bonds a second dragon, Andarna.
Two houses, one execution, one marriage back across it. The gold line is the wedding at the end of Onyx Storm; the blue line underneath is the dragon bond that forced Violet and Xaden together in the first place.

The other families worth knowing

Faces

What they actually look like

Straight from the books rather than from anyone's casting wishlist — which is what a host will ask about anyway. "Who has pink hair?" is a real trivia question.

Violet SorrengailA long braid of brown that fades to a steely, metallic silver at the ends. Pale skin, and pale hazel eyes that shift through blues and ambers. Small and physically fragile — joints that dislocate under strain.
Xaden RiorsonTall and heavily built, black hair, dark stubble, warm tawny skin, and gold-flecked onyx eyes. The tell is the diagonal scar bisecting his left eyebrow and catching the top of his cheek. A rebellion relic winds up his forearm.
Imogen CarduloPink hair, shaved on one side. Pale green eyes. Violet's line about her is that her beauty is only outmatched by her brutality.
Rhiannon MatthiasDark skin and dark curly hair that halos around her face when she wears it down.
Liam MairiTall and massively built, spiky light-blond hair, a prominent nose, blue eyes. Reads as a golden retriever, fights like anything but.
Dain AetosSoft brown eyes and a beard, with a scar peeking through it.
Ridoc GamlynFloppy brown hair, brown skin, on the smaller side.
Sawyer HenrickTall, lean and wiry, light complexion, freckles.
Garrick TavisBroad shoulders and hazel eyes.
Mira SorrengailTall and muscular, brown hair and brown eyes — built like the soldier she is.
Lilith SorrengailSheared golden-brown hair. Everything about her is regulation.
Jack BarloweIcy blue eyes — which come back rimmed in red once he's venin. The red rim is the series' universal tell.
Bestiary

The dragons

Dragons are identified by color and tail type, and the tail type is a favorite trivia hook. The breeds: morningstartail, daggertail, swordtail, scorpiontail, clubtail, and feathertail. Feathertails are small, rare, and considered useless in a fight — which is the joke, because Andarna turns out to be the most important dragon in the series.

Morningstartail

A spiked ball on the end. Tairn is one — remember this one above all.

Daggertail

A short blade. Sgaeyl, Feirge and Deigh are daggertails.

Swordtail

Longer and narrower than a dagger. Codagh, Cath, Sliseag and Aotrom.

Scorpiontail

Curls up and over into a stinger. Chradh and Baide.

Clubtail

Blunt and heavy, no blade at all. The bludgeon of the six.

Feathertail

Small, rare, and dismissed as useless in a fight. Andarna — and the joke is on everyone.

The mechanic everything hangs on

Tairn and Sgaeyl are a mated pair. That means Violet and Xaden physically can't stay far apart for long without their dragons suffering — the forced proximity is built into the magic, and it's the engine of the entire romance. Riders and dragons also share a mental link, which is why some of the funniest lines in the books are Tairn being witheringly rude inside Violet's head.

The plot

Book by book

Volume One 2 May 2023

Fourth Wing

Violet crosses the Parapet, survives the Gauntlet, and at Threshing bonds not one dragon but two — Tairn, whose previous rider died, and Andarna, a feathertail hatchling nobody expects to live. Bonding two is unheard of and makes her a target.

She spends the year hunted by her own classmates, chiefly Jack Barlowe. Her signet arrives late and turns out to be lightning, one of the rarest and most destructive. She kills Jack with it, dropping a turret on him after he tries to kill Liam.

Meanwhile she falls for Xaden, whose father led the rebellion her mother crushed, and who has been quietly running a resistance under everyone's nose. The war games send them to Athebyne, outside the wards, and then to Resson — where Violet finally sees what Navarre has been hiding: venin and wyvern. Liam's dragon Deigh is killed and Liam dies with him. Violet is poisoned, wakes in Aretia, and finds Brennan — dead for six years — standing over her saying welcome to the revolution.

Volume Two 7 November 2023

Iron Flame

Violet returns to Basgiath for second year knowing the truth, and spends half the book trying to prove it. She and her squad steal journals from the royal vault to learn how the original riders — the First Six — built the wards. She's caught, interrogated, and tortured by Major Varrish. Dain, of all people, gets her out, and she escapes to Aretia.

In Aretia the rebellion raises its own wardstone and forges the alloy daggers that can actually kill venin. Then Jack Barlowe — very much alive, now venin — destroys the wardstone at Basgiath, dropping the wards over all of Navarre.

The climax is a thousand wyverns against an unprotected Basgiath. Jesinia works out that the wards need seven dragon breeds, and Violet realizes Andarna is the seventh — she was never a black dragon. Violet is about to burn herself out powering the wardstone when her mother takes her place and dies doing it. The wards rise, the wyverns drop.

Final beat: Violet looks at Xaden and sees red rimming his eyes.

Volume Three 21 January 2025

Onyx Storm

Xaden channeled from the earth to save everyone, so he's now a venin initiate, hiding it, and the relationship is coming apart. Aretia's wards will only hold about six months. So Violet leaves the continent hunting the lost irids — Andarna's kind, the seventh breed — and any allies she can get.

The search crosses the isles: Deverelli, Unnbriel, Hedotis, and Zehyllna, through court politics, assassination attempts, and a lot of people who'd rather stay out of it. They do find the irids. The irids refuse to help.

Violet's second signet surfaces: dream-walking, a form of mind magic she has to hide, because mind-readers are illegal in Navarre. Andarna breaks their bond to stay with her own kind — then comes back when it counts.

It ends at the battle of Draithus, where the venin maven Theophanie has taken Mira hostage. Violet kills Theophanie with a dagger blessed at the temple of Dunne — it works because Theophanie was once Dunne's high priestess. Quinn is killed. Aaric's family sends a thousand soldiers from Zehyllna. And Xaden, watching Sgaeyl about to die, stops resisting and turns completely, unleashing the shadow storm the book is named for.

The last chapter: Violet wakes in Aretia missing twelve hours. There's an emerald ring on her finger and a marriage document signed by the high priestess. She asked Imogen to wipe the memory so nobody could pull it out of her head. Xaden married her to make her Duchess of Tyrrendor — legal cover — then vanished. Riders are dead, six dragon eggs are gone, Garrick is missing, and Commandant Panchek is exposed as the traitor. The note reads: "Don't look for me. It's yours now."

The enemy

The venin, explained properly

This is the lore question people get wrong, so it's worth thirty seconds. Riders draw magic through their dragons. Venin skip the dragon and draw it straight out of the earth — far more power, with no ceiling, at the cost of killing the land into grey dust and hollowing out the person. Once you channel, there is no way back.

Venin create wyvern: two-legged, mindless dragon-shaped creatures with no magic of their own. They're the foot soldiers. A wyvern dies like an animal; a venin dies reliably only to a blade forged from a specific alloy.

The four ranks, lowest to highest

InitiateJust channeled for the first time. Red rings around the eyes that come and go.
AsimA step up. Eyes shift red, veins show when they're agitated. This is what Xaden becomes.
SagePowerful, responsible for initiates, permanently red-eyed with spiderwebbed veins. Berwyn is one.
MavenThe top rank — the generals. None has ever been captured. Theophanie was one.

Navarre's leadership has known about the venin for centuries and buried it, letting Poromiel take the losses, because admitting what the wards are really for would mean admitting the war with Poromiel was a lie.

The other half of the books

The romance, plotted

Half the questions at a romantasy trivia night are relationship questions. Here's the map.

Violet & Xaden — the main event

Everyone else

The spicy chapters

A real trivia category at these nights. These numbers are compiled by the fandom rather than by the publisher, so treat them as very good guidance rather than gospel:

Useful counter-fact if the topic comes up: Onyx Storm runs 66 chapters, and the first two books have roughly three spicy chapters each.

Where teams lose points

The easy mix-ups

Similar names, similar places, one letter apart. This is the table to read last before you walk in.

PairThe first oneThe second one
Aretia / Athebyne Aretia — the Tyrrendan city that becomes the rebellion's base. Athebyne — the outpost beyond the wards the war games send them to in book 1.
Resson / Draithus Resson — the Poromish town in book 1 where Liam dies. Draithus — the Poromish city where book 3's final battle happens.
Deigh / Cath Deigh — red daggertail, Liam's. Killed at Resson. Cath — red swordtail, Dain's. Both are red; the tail is the tell.
Tairn / Sgaeyl Tairn — Violet's, black morningstartail, the huge one. Sgaeyl — Xaden's, navy daggertail. They're mates, which is the whole plot device.
Venin / wyvern Venin — the people. They channel from the earth and keep their minds. Wyvern — what venin make. Mindless, two-legged, no magic of their own.
Navarre / Poromiel Navarre — Violet's kingdom. Dragons, wards, and a very large secret. Poromiel — the enemy nation. Gryphons, and the ones actually being eaten by venin.
Signet / relic / rebellion relic Signet is your magical power. Relic is the mark your dragon leaves on your skin. Rebellion relic is different again — the mark on the 107 children of the executed rebels.
Lilith / Melgren General Lilith Sorrengail — Violet's mother. Storm wielder. Dies in book 2. General Melgren — the commanding general. Sees battle outcomes. Very much alive.
Aaric / Halden Aaric — really Prince Camlaen Aaric Tauri, the third son, hiding as a cadet. Halden — his brother, ahead of him in the succession.
Jack Barlowe / Dain Aetos Jack — tries to murder Violet outright, dies, comes back venin. Dain — the friend who betrays her trust rather than her body. Different kind of problem.
Parapet / Gauntlet / Threshing / Presentation Parapet is the bridge on day one. Gauntlet is the climbing course after. Threshing is when dragons choose. Presentation is when bonded riders are shown off.
Sorrengail siblings Mira is the older sister and a rider. Brennan is the brother presumed dead. Both are alive at the end of book 3. Their mother and father are not.
Outside the books

Real-world trivia

Trivia nights love the out-of-book questions, and they're the easiest points on the board.

Test yourself

Self-quiz

Tap a question to reveal the answer. Thirty-two of them — twenty-four right and you're carrying the team.

What makes Violet Sorrengail unique among riders?

She's bonded to two dragons — Tairn and Andarna — which had never happened before. She's also physically fragile, with joints that dislocate easily, and was raised to be a scribe rather than a rider.

What is Violet's signet? And her second one?

Lightning wielding, one of the rarest. In Onyx Storm a second surfaces: dream-walking, a form of mind magic she has to keep hidden.

What is Xaden Riorson's signet?

Shadow wielding. He also turns out to be an inntinnsic — a mind-reader — which is illegal in Navarre and which he hid from Violet.

Name Violet's mother, her rank, and her power.

General Lilith Sorrengail, commander at Basgiath, a storm wielder with the dragon Aimsir. She dies powering the wardstone at the end of Iron Flame.

Who are Violet's siblings?

Mira, a rider who manifests wards, dragon Teine — and Brennan, believed killed six years earlier, actually alive, a mender, running the rebellion out of Aretia.

What is the Parapet?

The narrow, unrailed stone bridge cadets must cross on conscription day to enter the Riders Quadrant. Falling kills you. It's the first filter of the year.

What happens at Threshing?

Dragons choose their riders. Cadets who aren't chosen are typically killed. The companion book due in 2026 is named after it.

What is a rebellion relic, and how many people carry one?

A shimmering mark twisting up from the wrist, borne by the children of the executed Tyrrish rebellion officers — 107 of them, the "marked ones." It was made by Codagh, Melgren's dragon.

What does the rebellion relic actually do?

When three or more marked ones are together, General Melgren can't see the outcome of what they do — which blinds his precognition. That's why gatherings of three or more are forbidden, and why the rebellion can function.

How does Liam Mairi die?

At the battle of Resson. His dragon Deigh is killed by a wyvern while protecting Tairn, and because a rider's life is bound to their dragon's, Liam dies too. Earlier in the book he'd already survived a stabbing by Jack Barlowe.

How does Jack Barlowe die — and does he stay dead?

Violet's newly manifested lightning brings a turret down on him. He does not stay dead: he returns in Iron Flame as venin and destroys Basgiath's wardstone.

What is a venin, and how does it differ from a rider?

A person who channels magic directly from the earth instead of through a dragon. Limitless power, drains the land to dust, destroys the soul. One-way — you can't come back.

List the four venin ranks in order.

Initiate → asim → sage → maven. Xaden becomes an asim. Theophanie is a maven.

What are wyvern, and what kills a venin?

Wyvern are the two-legged, mindless dragon-shaped creatures venin create; they have no magic of their own. Venin are reliably killed only by daggers forged from a particular alloy, made using a luminary.

Who is Aaric Graycastle really?

Prince Camlaen Aaric Tauri — King Tauri's third son — hiding as an ordinary cadet under a false surname. He slipped his guards after noticing they'd started carrying alloy daggers.

What is Andarna actually?

Not a black dragon at all — she's the seventh breed, an irid, thought lost. The wards need all seven breeds, which makes her the key to the entire defense.

Why can't Violet and Xaden stay apart?

Their dragons, Tairn and Sgaeyl, are a mated pair. Distance between the riders causes the dragons real distress, so the proximity is enforced by the magic itself.

How does Iron Flame end?

A thousand wyverns attack an unwarded Basgiath. Lilith Sorrengail gives her life to power the wardstone, channeling through Sloane's siphon. The wards rise and the wyverns drop. Then Violet notices red rimming Xaden's eyes.

Why does Violet leave the continent in Onyx Storm — and where does she go?

Aretia's wards will only hold about six months, so she hunts the lost irids and any allies she can find. The isles: Deverelli, Unnbriel, Hedotis, Zehyllna. She finds the irids; they refuse to fight.

Who kills Theophanie, and why does that particular weapon work?

Violet, using a dagger blessed at the temple of Dunne. It works because Theophanie was once Dunne's high priestess.

What is the "onyx storm"?

What Xaden unleashes at the battle of Draithus when he stops resisting and fully turns venin to save his dragon Sgaeyl — a wave of shadow that frees Sgaeyl and Tairn and kills everything in its path.

What does Violet wake up to on the last page of Onyx Storm?

Twelve hours of missing memory, an emerald wedding ring, and a marriage document — she and Xaden are married, making her Duchess of Tyrrendor. She'd asked Imogen to wipe the memory so it couldn't be read out of her. Xaden is gone, leaving: "Don't look for me. It's yours now."

What finally ends things between Violet and Dain?

He reads her memories by touch without her consent. He does kiss her in book 1, but she'd already moved on — the betrayal of trust is the real break.

Who is Cat Cordella to Xaden?

His former betrothed, from an arrangement predating the books. She's a gryphon rider from Poromiel.

Name a confirmed couple that isn't Violet and Xaden.

Rhiannon and Tara — on-again, off-again, strained by Rhiannon's rank and the secrets she has to keep. Rhiannon and Sawyer also had a brief no-strings thing after Threshing.

Who has pink hair shaved on one side?

Imogen Cardulo, with pale green eyes. She's also the one whose memory-wiping signet drives the ending of book 3.

What's distinctive about Violet's hair — and about Xaden's face?

Violet's braid is brown fading to metallic silver at the ends. Xaden has a diagonal scar bisecting his left eyebrow onto the top of his cheek, and gold-flecked onyx eyes.

Name Xaden's parents.

Fen Riorson, Duke of Tyrrendor, who led the Tyrrish rebellion and is called the Great Betrayer — and Talia Riorson. Fen was executed by Violet's mother.

How did Violet's father die?

Asher Sorrengail, a lieutenant colonel and a scribe, died of a heart attack about a year before Fourth Wing — from grief, after Brennan was believed killed.

What tail type is Tairn? What about Sgaeyl and Andarna?

Tairn is a morningstartail (spiked ball). Sgaeyl is a daggertail. Andarna is a feathertail — small, rare, and written off as useless, right up until she turns out to be the seventh breed.

Who is Sloane Mairi, and why does she fear her own power?

Liam's younger sister and a siphon. Lilith Sorrengail channeled through her to power the wardstone and died doing it — so Sloane carries that.

How many Empyrean books are planned, and what's next?

Five. Three are out. Threshing Day, a thirteen-story companion, is due 29 September 2026. Book 4 is untitled with no release date.
