Jeyrha — VESSELBORN Codex

Jeyrha

The Green Jewel

Location: Southwest of Geba, south of Ngorrhal, west of Berinu, north of Manalheim

Population: ~3 billion

Gender Ratio: More women than men, less severe than the planetary 25:1

Bordering Waters: Ngorrhal Ocean (north), Manalheim Ocean (south and southwest)

Relay Infrastructure: Single mega relay, several large hubs

Climate: Lush tropical, with fungal forests in the south under Saethern's permanent light

Jeyrha is the southern Green Jewel of the Geban Empire, peacefully assimilated during the Imperial Conquest when Xerik Haavu designed the Haavu Cannon Systems, securing integration without bloodshed and elevating the Haavu family to the most prominent non-imperial family on the planet. Jeyrha was never conquered. Its naming conventions were never replaced. Its population was never systematically culled. The gender ratio is less severe than the planetary average as a result. The continent's Jeyrhan heritage runs deeper than its borders. Southern immigrants brought by Therik to the Geba continent thousands of years before the Empire reached Jeyrha settled in Varena, and their descendants produced Architect Varenth Solarn, who was Jeyrhan, born and raised on the Geba continent. He built the first relay systems outside the origin continent. The entire planetary relay network traces back to a Jeyrhan descendant.

Engineering and Science

Jeyrha hosts the planet's premier engineering guilds and is the undisputed leader in biological sciences and ecological engineering. The Jeyrhan Bio-Engineering Consortium leads planetary advancements in weapons, vehicles, energy, and intelligence systems. Children on Jeyrha grow up learning far more than cellular principles. Most do not claim to be bioengineers instead of pilots, singers, or standard engineers, but the fact is that the continent produces a massive proportion of the planet's bioengineers relative to its population. The center of advanced medicine was originally on Jeyrha before it moved to the capital during the Era of Early Stagnation, driven by the population density of Karesh rather than any deficiency in Jeyrhan capability.

Cities and Governance

Reyhuul is pragmatic, mechanical, and farming-focused. Reykhaal is academic, an innovation hub built around massive academies that train elite bioengineers and artists. Both pulse with hedonistic festivals celebrating art and indulgence. Governance is oligarchic, dominated by the Haavu family and other established families who maintain power through methods that outsiders rarely understand until they have already been destroyed by them. Jeyrha is open to foreigners, and its melodic speech and light features reflect a culture of exchange and precision.

Terrain and Light

The continent is lush year round, consistently warm and green under strong illumination from Izhara and Zhaerys. Southern Jeyrha always catches some of Saethern's fixed light and its effects, producing fungal forests in the southern regions where the permanent glow encourages growth patterns not found anywhere else on the planet except Saethera itself. Thriving reefs and vast inland fields are sustained through ecological engineering. Jeyrha remains a beacon of harmonious integration and biological advancement.

About Vesselborn

Vesselborn is the story of Geba — a world that has carried an empire for six thousand years.

It begins with Vaer’karesh, who unites five nations into the first empire and fixes a common language and law. Across the ages, the empire fights and finally breaks Thazvaar, welcomes Jeyrha through engineering and diplomacy, and liberates Berinu by choice. In Ngorrhal, the people of the mountain passes lose their ancestral name and are permanently renamed the Frost Sentinels, whose strength helps secure imperial rule. The Haavu cannon systems cement that dominance.

At its height, the empire spans continents and raises relay towers that bind cities, coasts, and passes into one network. Assassinations and civil wars follow — the Fracture — but the answer is not a vacuum. The Shadow Rule forms from imperial networks and manufactures peace, ending the warlord broadcasts and taking the world back from collapse. They are the empire made quiet: continuity without ceremony.

Today, the Shadow Rulers still govern from the background while the Energy Wars — covert struggles over power grids and relays in uncivilized regions — decide who controls energy, transport, and culture.

Stories range from relay-field defenses and inland recoveries to city governance and frontier resettlement; from rail lines and air programs that stitch regions together to festivals and work crews where culture and politics collide; from Frost Sentinel memory to families choosing the safety of hub clearings or the risk beyond the grid.

This is Geba.
It began in silence.
It has not yet ended.
