Physiology

The Jeyrhan are the smallest human population on Geba. Women range from 4'6" to 5'2". Men rarely reach 5'8". Most carry light brown hair and grey-blue eyes, though appearance varies between regions. Their frames are naturally small. A Jeyrhan woman may weigh 90 lbs without being considered underweight for her build. The women are known across the planet for exotic hairstyles of extraordinary length, worn in elaborate arrangements that draw attention in ways their bodies alone do not.

The population can produce larger and more athletic individuals, but it does so uncommonly. Yui Jersuul stands at 5'5" and 170 lbs, tall for a Jeyrhan woman and muscular in a way that most of her people are not. Her brother Ongpek reaches 5'11" and 220 lbs. Tolin Ruul is an extreme outlier at 6'1", weighing 161 lbs before contracting and 205 lbs by the time of their first inland contract. These individuals confirm the genetic range exists. They do not represent the population.

What They Build

The Jeyrhan are responsible for more of the infrastructure, technology, and systems that sustain modern civilization than any other single group on the planet, including the imperials. The Jeyrhan Bio-Engineering Consortium leads planetary advancements in weapons, vehicles, energy, and intelligence systems. Saojuul Labor runs automation wherever work needs doing. Xerik Haavu designed the Haavu Cannon Systems that secured Jeyrha's peaceful assimilation and elevated the Haavu family to the most prominent non-imperial family on the planet. And the consequence that preceded all of it: the southern immigrants that Therik brought 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. If you removed what the Jeyrhans built, the planet would not function.

How They Live

Jeyrha joined the Empire peacefully. It was never conquered. Its naming conventions were never replaced. The continent is open to foreigners and has been since before assimilation. Those from Reyhuul are pragmatic, focused on farming and practical devices. Those from Reykhaal are academic, based in massive cities with world-renowned academies that train elite bioengineers and artists. Children across Jeyrha grow up learning far more than cellular principles. Most do not claim to be bioengineers, choosing instead to be pilots, singers, or standard engineers, but the continent produces a massive proportion of the planet's bioengineers relative to its population regardless.

Both regions celebrate with hedonistic festivals that would appear incompatible with the precision and discipline their work demands. The festivals are not a contradiction. They are the other half of the cycle. Professional rivalries, courtship conflicts, and social tensions are paused during celebration and often resolved within them. The culture fights in silence and reconciles in excess.

Courtship

When a Jeyrhan identifies a partner of interest, they invest sustained effort over extended periods. The offers they make can be so subtle and indirect that the target has no idea they were made. The Jeyrhan who made the offer considers it made regardless of whether anyone else perceived it. If another person moves toward that individual, the Jeyrhan treats it as encroachment on territory they have already claimed, even if the claim was never visible. With the planetary gender ratio making partners scarce, this is not occasional. It is constant. Many young Jeyrhans seeking their first partners end up in prolonged social conflicts over individuals who may not even realize someone is interested.

Where romance is not reciprocated, the cycle intensifies rather than resolving. The same cognitive architecture that allows a Jeyrhan engineer to spend years perfecting a single propulsion system becomes consuming when the objective is a person who cannot be engineered into reciprocating. For many, this leads to obsession and instability over a single individual. The culture provides no mechanism for disengagement outside of the festivals, which offer temporary relief but not resolution. When the celebration ends and the target still does not reciprocate, the pursuit resumes with greater intensity.

Professional Rivalry

The territorial instinct extends into professional environments. Rather than stealing schematics or openly attacking a rival's work, a Jeyrhan will embed altered numbers or changed formulas into another person's patent and allow them to present it publicly, discrediting them without confrontation. This is common practice. The same people who sabotage each other's work attend festivals afterward as if nothing happened and are quick to get along again. The sabotage is not personal the way other populations would interpret it. It is simply how competition functions among them. The oligarchic families that dominate Jeyrhan governance, particularly the Haavu, maintain power through exactly these methods. Anyone entering Jeyrhan political structures without understanding the dynamics is destroyed before they realize what happened.

Combat

The Jeyrhan are not fighters. They are not warriors. They do not pilot killing machines unless those machines can be raced. When asked about this directly, they state it plainly: they are wired to create, not to contest. The rare exceptions who choose combat are notable precisely because they are exceptions. Yui Jersuul is the greatest arena duelist alive. Texen Berihaal contracts in the Energy Wars. The overwhelming majority build, design, engineer, and then go home and celebrate.
