Jeyrha
Alias: The Green Jewel Location: Southern Geba (across ocean from Ngorrhal)
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 prominence. Masters of biological sciences and ecological engineering, they sustain thriving reefs and vast inland fields. Southern Jeyrha always catches some of Saethern’s light and its effects. Cities like Reyhuul (pragmatic, mechanical, farming-focused) and Reykhaal (academic, innovation hub) pulse with hedonistic festivals celebrating art and indulgence. Jeyrha hosts the planet’s premier engineering guilds and was once the Empire’s medical center before relocation to the capital. It houses a single mega-relay, supplemented by several large hubs. Open to foreigners, its melodic speech and light features reflect a culture of exchange and precision, where children learn cellular principles. 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.
