The Onyx Storm map expands the world readers first discover in Fourth Wing and Iron Flame, taking them beyond Navarre and Poromiel to the mysterious Isle Kingdoms. The printed map of the Continent shows important regions such as Navarre, Poromiel, and the Barrens, while Onyx Storm introduces five major Isles: Deverelli, Unnbriel, Hedotis, Zehyllna, and Loysam. However, their exact geographical positions are not officially mapped, leaving readers to piece together the wider Empyrean world from the books.
What Does the Onyx Storm Map Show?
The Onyx Storm map covers the Continent of Amaralis, including the kingdoms of Navarre and Poromiel and the ruined region known as the Barrens. It also introduces five major Isle Kingdoms across the surrounding seas: Deverelli, Unnbriel, Hedotis, Zehyllna, and Loysam. The printed map shows the Continent, but the Isle Kingdoms are described primarily through the story rather than displayed on an official map.
Understanding the Empyrean World: From Fourth Wing to Onyx Storm
Rebecca Yarros gradually expands the geography of the Empyrean series across its first three books. Each installment gives readers a broader understanding of the world, its political divisions, and the threats affecting its kingdoms.
Fourth Wing: Discovering Navarre and Poromiel
In Fourth Wing, readers primarily experience the world through Violet Sorrengail’s life at Basgiath War College in Navarre.
The Continent is divided between two major kingdoms:
- Navarre: A mountainous kingdom known for its dragons, military structure, and protective wards.
- Poromiel: A neighboring kingdom associated with gryphon riders, fliers, and a long history of conflict with Navarre.
The Barrens also appear on the geographical map, although their history and significance become clearer as the series progresses.
Iron Flame: Expanding the Geography and Political Conflict
Iron Flame takes readers beyond the familiar surroundings of Basgiath.
The story introduces more details about Tyrrendor, Aretia, the rebellion, and the political relationships between Navarre and Poromiel.
Readers also learn more about the Aretian wards, the importance of Aretia’s wardstone, and the geographical threats facing the Continent.
The Isle Kingdoms are mentioned, but their cultures and political systems are not explored in the same detail as they are in the third book.
Onyx Storm: Discovering the Isle Kingdoms
Onyx Storm significantly expands the known world.
Violet and her companions travel beyond the familiar Continent in search of allies and information about the Irids. Their journey introduces different island cultures, religious traditions, rulers, and political systems.
The five major Isle Kingdoms become an important part of the story:
- Deverelli
- Unnbriel
- Hedotis
- Zehyllna
- Loysam
These locations reveal that the world of the Empyrean series extends far beyond the territories readers initially associate with Navarre and Poromiel.
The Continent of Amaralis Explained
The Continent is the main landmass in the Empyrean series. It contains Navarre, Poromiel, and the Barrens.
The Emerald Sea lies to the north, while the Arctile Ocean extends to the south, beyond which the Isle Kingdoms become important to the story.
Navarre
Navarre is a mountainous kingdom protected by magical wards and home to dragon riders.
Its six provinces are:
- Tyrrendor
- Luceras
- Calldyr
- Morraine
- Deaconshire
- Elsum
The Tauri royal family rules Navarre from Calldyr City.
Navarre’s military system is closely connected to Basgiath War College, where cadets train in four different Quadrants.
Poromiel
Poromiel is Navarre’s neighboring kingdom and has historically been involved in a prolonged conflict with it.
Unlike Navarre, which relies on dragons and dragon riders, Poromiel is known for its gryphon riders, commonly called fliers.
Poromiel has three major provinces:
- Krovla
- Braevick
- Cygnisen
The kingdom’s geography includes plains, farmland, marshes, and important coastal settlements.
Poromiel’s relationship with the Isle Kingdoms is also important because it has maintained connections and trade with the Isles during periods when Navarre was isolated from them.
The Barrens
The Barrens is a ruined and largely deserted region of the Continent.
Its history is closely associated with the venin and the draining of magic from the land.
The region becomes increasingly important in Iron Flame and Onyx Storm, as readers discover more about the relationship between magic, the venin, and the history of the Continent.
The Barrens should not be treated as simply an empty area on the map. Its history is connected to the wider conflict affecting the Empyrean world.
Navarre Map: Important Locations in Fourth Wing and Iron Flame
Navarre contains some of the most recognizable locations in the Empyrean series.
Basgiath War College
Basgiath War College is located in Morraine, Navarre.
It is where Violet begins her training and where cadets prepare for military service.
The college has four main Quadrants:
- Riders Quadrant: Trains dragon riders.
- Scribe Quadrant: Trains scribes who preserve and document knowledge.
- Healer Quadrant: Trains healers and medical personnel.
- Infantry Quadrant: Trains soldiers for ground combat.
The Vale and dragon hatching grounds are also associated with Morraine, making the province especially important to the dragon-rider world.
The Vale
The Vale is the home of Navarre’s dragons and contains their hatching grounds.
It plays an important role in dragon bonding, dragon breeds, and the traditions surrounding the Riders Quadrant.
Tyrrendor and Aretia
Tyrrendor is one of Navarre’s most important provinces.
Its capital, Aretia, is closely connected to the rebellion and the history of the Riorson family.
Important locations and features associated with this region include:
- Aretia
- Riorson House
- Cliffs of Dralor
- Medaro Pass
- Lewellen
- Aretian wards and wardstone
Aretia becomes particularly important in Iron Flame, when its wardstone and hatching grounds play a role in the wider conflict.
The Cliffs of Dralor form an important geographical barrier near the border with Poromiel. Medaro Pass is a known route through this difficult terrain.
Calldyr City
Calldyr City is the center of Navarre’s royal power.
It is associated with the Tauri royal family and the kingdom’s political leadership.
Elsum and Other Provinces
Elsum is another important province in Navarre, while Luceras and Deaconshire contribute to the wider geographical and political structure of the kingdom.
Not every province receives the same amount of attention in the novels, so readers should distinguish between locations with detailed story roles and those that are mainly identified geographically.
Poromiel Map: Important Cities and Locations
Poromiel is particularly important in Iron Flame and Onyx Storm because of its political relationships with Navarre and its role in the fight against the venin.
Krovla
Krovla is one of Poromiel’s three provinces.
It is associated with Viscount Vicarus Tecarus and the city of Cordyn.
Cordyn
Cordyn is home to Tecarus’s estate and palace.
The location is politically important because of Tecarus’s influence and his relationships with the neighboring kingdoms.
Draithus
Draithus is a major coastal city in Poromiel.
It is described as a populous settlement with high walls and a distinctive spiral tower.
Its importance increases in Onyx Storm, where it becomes one of the significant locations connected to the story’s military and political developments.
Braevick
Braevick is another Poromish province.
It includes Zolya, an important city associated with Cliffsbane Flight Academy.
Zolya and Cliffsbane Flight Academy
Zolya is home to Cliffsbane Flight Academy, where Poromiel’s gryphon fliers train.
The academy is important to understanding Poromiel’s military structure and its relationship with Navarre’s Riders Quadrant.
Cygnisen
Cygnisen is the third major province of Poromiel.
It contributes to the kingdom’s geographical and political identity, although the novels provide fewer detailed descriptions of its individual settlements.
The Barrens: Why This Region Matters
The Barrens deserves its own place in an Empyrean series map guide because its importance goes beyond geography.
The region is associated with drained land, the history of venin, and the wider magical conflict.
In Iron Flame, the threat of venin becomes more immediate, and readers begin to understand that the danger is not limited to the boundaries originally described in Navarre’s history.
The Barrens therefore represent an important part of the Continent’s past and the larger threat facing its inhabitants.
Onyx Storm Map of the Isles: All Five Isle Kingdoms Explained
One of the biggest geographical developments in Onyx Storm is the introduction of the Isle Kingdoms.
These islands have their own rulers, cultures, religious traditions, and political interests.
Although the books provide clues about their locations and travel routes, readers do not receive a complete official map showing the exact positions of every Isle.
Deverelli: The Isle of Merchants
Capital: Matyas
Ruler: King Courtlyn
Deverelli is known for its merchants, trade, and political neutrality.
It is associated with the exchange of goods and information, making it an important location for diplomatic relationships.
Unlike the other major Isles, Deverelli is not primarily associated with one of the four patron gods discussed in the story.
Its southern position and its connections with the Continent make it an important starting point for understanding the Isle Kingdoms.
Unnbriel: The Isle of Dunne
Capital: Eistol
Ruler: Queen Marlis
Patron deity: Dunne, Goddess of War
Unnbriel is associated with Dunne, the Goddess of War.
Its culture places considerable importance on strength, military traditions, and the ability to prove one’s worth.
Trial by combat is an important part of its customs, particularly for visitors seeking an audience with its leadership.
Unnbriel provides a useful example of how religious beliefs influence the political and social structures of the Isle Kingdoms.
Hedotis: The Isle of Wisdom
Capital: Vidriys (verify the spelling in your edition)
Government: A triumvirate
Patron deity: Hedeon, God of Wisdom
Hedotis is associated with Hedeon, the God of Wisdom.
Unlike kingdoms governed by a single monarch, Hedotis is ruled by a triumvirate consisting of Faris, Nairi, and Roslyn.
The island’s political traditions emphasize knowledge, wisdom, and careful decision-making.
Visitors seeking an audience with the ruling triumvirate must undergo a trial of wisdom.
Hedotis is especially important because its political system differs from the monarchies found elsewhere in the Empyrean world.
Zehyllna: The Isle of Zihnal
Capital: Xortrys (verify the spelling in your edition)
Patron deity: Zihnal, God of Luck
Zehyllna is associated with Zihnal, the God of Luck.
It stands out among the Isle Kingdoms because magic is present there, although it is described as less powerful than the magic found on the Continent.
The island’s customs include gift-related traditions and an audience with its queen.
Its relationship with magic and the traditions surrounding Zihnal make it one of the more distinctive locations introduced in Onyx Storm.
Loysam: The Isle of Loial
Capital: Not confirmed
Ruler: Not confirmed
Patron deity: Loial, God o
