The Empyrean Series, Explained

Unofficial fan guide · Last updated October 3, 2026

◆ What is The Empyrean?

The Empyrean is the title of Rebecca Yarros's fantasy romance series — the saga that opened with Fourth Wing in 2023 and now spans three novels, a short story collection, and more on the way. It is also a #1 New York Times bestseller on the strength of its first book alone, and it essentially defined the "romantasy" wave of the mid-2020s. But "Empyrean" is also a word inside the world itself, and that double meaning is the point.

Within the books, the Empyrean is the dragons' own government: the ruling council of dragonkind, which operates entirely outside human authority. Dragons in this world are ancient, fiercely intelligent, and politically organized. They live in dens, they keep their own laws, and when the Empyrean holds a meeting, even a dragon's bonded rider learns nothing about it. The series is named after that institution — the saga's title and the dragon government's name are one and the same.

◆ Why "Empyrean"?

The title signals where the real power sits. Humans run the war college, the generals, and the armies — but the dragons hold the ultimate authority. A cadet at Basgiath can train for years and still be rejected, ignored, or incinerated by a dragon who simply does not choose them. In a story about people trying to earn a dragon's approval, the highest court in the land is not a human one. Calling the series The Empyrean puts the dragons at the center from the very first word.

◆ The core setting

The Empyrean series takes place in the kingdom of Navarre, under permanent threat from its neighbor Poromiel, and revolves around Basgiath War College — the academy where future riders are forged (and frequently killed). A handful of rules hold the whole world together, and they're worth knowing before page one:

Dragons choose riders

A bond is never forced. A dragon decides who it will carry — the whole premise of the series rests on the fact that no human gets a say. This one rule drives every character's arc: you cannot earn a dragon by merit, only by being the kind of person one decides is worth carrying.

Threshing and signets

Threshing is the annual ceremony, held every October 1, where willing dragons fly down to the valley and evaluate the surviving cadets. Survive it and you're bonded for life — and the bond grants each rider a signet, a personal magical ability. Violet Sorrengail channels lightning, Xaden Riorson commands shadows, and no two signets are quite alike. The signet is the bond made visible: proof that the dragon's power now flows through a human.

The war, the wards and the venin

Basgiath exists because Navarre is at war, and its riders are the front line. Six hundred years ago, the First Six riders allied with dragons and raised the wards that protect the kingdom — magical barriers that keep out the venin, magic-draining sorcerers who threaten everything the riders protect. As the series progresses, the wards fail, the war escalates, and the venin stop being a bedtime story and become the story.

The gryphon fliers of Poromiel

Navarre is not the only kingdom with aerial cavalry. Poromiel fields gryphon riders, called fliers, whose gryphons bond through a different, harsher magic — one that drains them. The fliers complicate every assumption the series makes: the "enemy" is not a monolith, and the rivalry between dragon riders and fliers becomes one of the most morally tangled threads in the later books.

◆ The key characters

Violet Sorrengail

The protagonist. Trained for the scribe's path, she is thrown into the Rider's Quadrant instead, and defies every expectation by bonding two dragons: the black dragon Tairn and the young feathertail Andarna — a situation with no precedent that anyone at the college can recall. Her signet is lightning, which is about as on-the-nose as it sounds. Between a body that was never built for the quadrant and a will that refuses to lose, Violet is the engine the whole series runs on.

Xaden Riorson

Violet's partner and a wing leader, whose shadow signet lets him command darkness itself. His dragon is Sgaeyl, one of the most powerful blues in service — and Sgaeyl is mated to Tairn, which means the two leads' romance comes with two extremely opinionated dragons attached. Xaden carries the series' moral tension: a leader of the rebellion's children, forever trying to hold the college's trust while hiding what he actually believes.

The wider cast

Around them the books build one of the genre's deepest ensembles: General Lilith Sorrengail, Violet's mother, a storm-signet general on a brown dragon named Aimsir; Violet's sister Mira (green dragon, ward-expanding signet) and brother Brennan (orange dragon); her friends Rhiannon, Ridoc, Sawyer and Imogen; the Mairi siblings Liam and Sloane; Dain Aetos, Bodhi Durran, Garrick Tavis and Aaric Graycastle; and the series' most reliable antagonist, Jack Barlowe. Every one of them shows up in the Threshing Day collection, each telling their own version of the ceremony.

Why the dragons matter as characters

What sets Fourth Wing apart from most dragon fantasy is that dragonkind's dragons are characters in their own right — ancient, opinionated, politically organized, and utterly unwilling to be treated as mounts. Tairn's dry sarcasm and Sgaeyl's cold authority are as memorable as any human line in the books, and the mate bond between them quietly drives the romance between Violet and Xaden. That is why a whole corner of the fandom cares less about the plot and more about what the dragons think.
