The Vale, in seven choices
Threshing is the day the dragons choose. You walk into the Vale as a first-year cadet, answer seven scenes, and find out which dragon bonds you — or which one burns you. A full run takes about three minutes, needs no account and no email, and can be replayed the moment it ends.
What happens underneath is a small, honest simulation. Every choice leans on one of four traits; the Vale weighs them, and a dragon's colour, tail, name, age and lineage fall out of that weighing. Nothing is uploaded anywhere: the run happens in your browser, and the dragons you bond are kept on your own device.
How the dragonkind threshing day game works
- Enter the Vale. One tap starts Threshing. Nothing to install, no account.
- Make seven choices. Each scene tests courage, cunning, loyalty, or fury.
- Survive or burn. Bold choices raise the odds of fire — and of a rarer dragon.
- Take your dragon. Name, colour, tail, sex, age, lineage and a signet hint, on a card you can save or share.
Four traits decide one dragon
Courage, cunning, loyalty and fury. The trait you lean on most sets the dragon's colour. The runner-up sets the tail. A rare tie, or a lucky roll, produces a morningstartail instead — and the boldest runs are also the ones most likely to end in fire, so the careful route through the Vale is a real strategy rather than a formality.
Because every run is a fixed sequence of seven answers, a result can be written down and replayed exactly. That is what the share code under each dragon card is for: hand someone the code and they can see the same dragon you did, choice by choice.
Dragon colours and tails you can bond
Six colours and five tail types make thirty dragon types in all. Your strongest trait points at a colour; your second strongest points at a tail.
The five tail types
A morningstartail is the rare one: any colour carrying it jumps a rarity tier.
How the colour is actually picked. Each trait you leaned on is counted and squared, so a run that keeps returning to one trait is pulled hard towards that trait's colour, while a scattered run stays unpredictable. Blue and black sit outside that weighting entirely — they get their own small roll, which is why they stay rare however you play. Today's Vale can also double the odds for one colour; the chip above the game tells you which.
How the tail is picked. The second strongest trait chooses between swordtail, daggertail, clubtail and scorpiontail. About one bond in ten produces a morningstartail instead, and the odds rise on a lucky path.
What each rarity actually means
Rarity here is a rule rather than a mood. It is decided entirely by the pair of colour and tail, so you can tell what you are chasing before you ever roll it:
- Common — one of the four workaday colours with a workaday tail. The large majority of bonds.
- Uncommon — any colour at all carrying a morningstartail.
- Rare — a blue dragon.
- Epic — a black dragon, or a blue one with a morningstartail.
- Legendary — black with a morningstartail, and nothing else.
Played across every one of the 16,384 possible choice sequences, that works out at roughly 79% Common, 8.8% Uncommon, 7.3% Rare, 4.5% Epic and 0.4% Legendary. A Legendary is about a one-in-250 bond, which is why the card is worth keeping. Your own stubbornness is recorded too: every result card says which attempt finally bonded you.
Your wing, section and squad
The official game assigns every cadet a wing, a section and a squad before they ever reach the Vale, and shows them in your profile. This simulator does the same, minus the sign-up: your assignment is derived from a stable anonymous id kept in your browser, so it stays the same for you and differs from everyone else's. You will see it above the game as Cadet · Third Wing · 2nd Section · Squad 4, and again on the dragon card you save.
This simulator and the official Dragonkind game
The official Threshing Day game is Dragonkind, which opened on 1 October 2026 and asks for an email address before you enter the Vale. This page is a fan-made simulator with its own story and its own dragons. The quickest honest comparison:
| Official Dragonkind | This simulator | |
|---|---|---|
| Before you play | email address and a verification code | nothing at all |
| Rider identity | wing, section and squad assigned at sign-up | same fields, derived from a local id |
| After you are burned | Threshing locks for four hours | instant retry |
| Story | original, written for the game | original to this site |
| Your dragon | name, colour, tail, sex, age, lineage | the same fields |
| Where it runs | dragonkind.com | this page, in your browser |
What the two share is the premise: dragons choose, dragons refuse, and no route through the Vale is guaranteed. Both work from six colours and five tail types. What differs is the machinery. The official game has never published how it decides, and players report that identical choices can end differently; the simulator on this page uses a rule you can read, which is exactly what makes a shared code reproduce the same dragon every time.

What is Threshing Day?
Threshing Day is the day first-year cadets walk into the Vale and the dragons decide who becomes a rider. It sits at the centre of Rebecca Yarros’s Empyrean collection Threshing Day, published on 29 September 2026 — thirteen stories from thirteen riders, one day in the Vale — and of the official Dragonkind game that followed it on 1 October. The page you are on is a free fan simulator: its Vale is not the official one, and its dragons are its own.
Threshing Day game FAQ
Do I need to sign up to play?
No. The simulator on this page has no account, no email and no waiting after you are burned. Everything runs in the page.
How many choices does a run take?
Seven. Each scene offers four answers, and each answer leans on courage, cunning, loyalty or fury. The whole run takes about three minutes and can be replayed immediately.
Why did my dragon burn me?
Refusal is part of Threshing. On the official game most attempts end in fire, which is why the four-hour lock stings; here, odds are shifted by how boldly you play, so a cautious run usually bonds within a couple of attempts while a reckless one can take eight. Either way you rise again instantly.
How long do I wait after dying on Dragonkind?
Every death locks Threshing on the official game for four hours. Time it however you like — here you can keep playing while you wait.
Can I get a black dragon?
Black is the rarest colour and only appears on its own small roll, so there is no sequence of answers that guarantees it. Black with a morningstartail is the only Legendary result, at about 0.4% of bonds.
What is a morningstartail?
The fifth tail type, and the one that lifts a dragon a tier: a workaday colour carrying it becomes Uncommon, blue becomes Epic, and black becomes Legendary. Roughly one bond in ten has one.
How are the dragon names made?
From an original pool of Gaelic-inspired roots assembled in three parts — about 22,880 possible names — so two riders rarely meet the same dragon. Age, sex and lineage are generated the same way.
Can I keep the dragons I bond?
Yes. Every bond is stored locally in your browser and drawn on a shareable card; nothing is sent anywhere. Saving the card gives you a 1080×1350 image you can post.
Does it work on a phone?
Yes. The whole game is one page, about 50 KB, with no install, no video and no third-party scripts — it plays the same on a phone as on a desktop.
Is this the official Threshing Day game?
No. This is an independent fan site, not affiliated with Rebecca Yarros, Entangled Publishing, Red Tower Books or Dragonkind. The official game is at dragonkind.com.
Is there a Fourth Wing dragon quiz here?
Yes — the seven choices work as a short Fourth Wing dragon quiz. Your answers decide a colour, a tail and the dragon that bonds you, and the result card names all three.
