Humans

Humans (Homo sapiens) are are a sentient species native to Earth, and the most abundant and widespread species of the Orion Arm in the Milky way Galaxy. Members of the species are mammals and part of the primate family, possessing four limbs and a bipedal body plan that allows upright movement and the use of their upper limbs for precise object handling. Human hands, equipped with opposable thumbs, support fine motor control and tool use, which has been central to their survival and expansion. Although physically weaker than many other known species, humans compensate through adaptability, endurance, coordination, and complex social behavior. They remain the only surviving species of their genus and show no biological subspecies despite long-term planetary dispersal.
Human civilization first developed on Earth, where early technological and social growth eventually led to industrialization, global communication, and planetary governance. Population pressure, resource strain, and scientific advancement drove humanity beyond its homeworld, first into the wider Sol System and later to permanent settlements across multiple planets and moons. The discovery and application of advanced propulsion and terraforming technologies marked the beginning of true interstellar expansion. This period saw the establishment of large political structures to manage humanity’s growing reach, most notably the United Nations Federation and the New Soviet Union, which together came to govern Earth and the majority of human colonies. These systems did not erase national or cultural identity but layered planetary and interstellar authority over existing human divisions.
The invention of faster-than-light travel and the Ward Translight Engine initiated what later became known as the Colonial Era, a period of rapid settlement beyond the Sol System. Early colonies, later classified as the Inner Colonies, were founded under strict selection standards and enjoyed relative stability and prosperity. As travel became cheaper and more accessible, expansion accelerated into the Outer Colonies, where regulation was weaker and populations more diverse. While this era was initially marked by optimism and growth, political imbalance between Earth, the Inner Colonies, and the Outer Colonies gradually deepened. Economic dependence, military oversight, and unequal representation fostered resentment, eventually leading to widespread unrest and rebellion.
By the late 27th century, these tensions erupted into open conflict between colonial populations and centralized authority, forcing the United Nations Federation to rely increasingly on the United Space Command to maintain control. These internal wars claimed millions of lives and strained human society across multiple systems. Before these conflicts could fully resolve, humanity faced an external existential threat with the outbreak of the Human–Hivivian War. During this conflict, humanity did not stand alone. Formal alliances were established with the Caniic Hierarchy, facilitated and mediated by the Tigriic, whose diplomatic influence proved critical in unifying disparate powers. Human forces were further supported by the industrial and navigational expertise of the Velmari, the diplomatic and humanitarian intervention of the Staalzi, and by strategic cooperation and postwar engagement with the Asiel. The scale and severity of the war eclipsed earlier struggles, resulting in the destruction of entire colonies and the loss of much of the Outer Colonial population. Information surrounding the war was tightly controlled, but its effects reshaped human space politically, militarily, and psychologically.
In the aftermath, humanity remains widespread but deeply scarred. Technologically advanced yet socially fragmented, humans continue to rely on centralized military power while maintaining formal alliances with their wartime partners. These relationships would later crystallize into a broader interstellar framework through the formation of the United Coalition of Races, intended to prevent future large-scale wars and manage cooperation between allied species. Despite internal division and repeated large-scale conflict, humans persist as a highly adaptive species driven by curiosity, survival instinct, and the ongoing desire to understand and control their environment. Their history is defined less by stability than by recovery—each expansion followed by collapse, and each collapse followed by renewed effort to rise again.

Biology

Anatomy and physiology

Humans, are mammals, and share common features with other large apes. They are warm-blooded and give birth to live offspring, providing nourishment through milk. With their five fingers, including an opposable thumb, humans have an advantageous hand structure that facilitated early tool-making. In terms of circulatory system, humans have a closed network consisting of one heart and blood vessels. Their red blood is due to hemoglobin, which contains iron. Humans possess two lungs that primarily function in a nitrogen-oxygen based atmosphere.

Life cycle and Reproduction

Human reproduction occurs through internal fertilization, typically via sexual intercourse. However, assisted reproductive technology procedures can also aid in conception. The gestation period for humans is around 38 weeks, but the length of a normal pregnancy can vary by up to 37 days. Compared to other species, human childbirth is considered risky and prone to complications and deaths. This is partly due to the fact that the size of the fetus's head is more closely aligned with the size of the pelvis and contributes to the often painful and prolonged labor experienced by human mothers, which can last for more than 24 hours.

Culture

Humanity remains multicultural among its still marginally independent nations on both Earth and interplanetary colonies. The colonization of other planets has also lead to the development of "colonial cultures". While some colonization efforts begin as multicultural endeavors, others saw a dominant influence from a specific region or nation on Earth. This influence often shapes the culture of that colony. Most people consciously hold onto their Earth heritage as national pride, with colonial cultures retaining some distinct traits of their origins while others fade or transform.

Language

English is the primary language among humans on Earth and throughout her colonies, it coexists with a wide range of national, regional, and minority languages that continue to thrive in everyday use. Though this can vary between nations and colonies with many locals choosing to speak in their native or historical language.

Naming Conventions

Human naming conventions are deeply rooted in cultural, linguistic, religious, and familial traditions. Despite the wide diversity in naming practices across human populations, the use of personal names to establish identity, denote heritage, and organize social roles remains universal. The most common structure consists of a given name (also known as a first name or personal name) and a family name (or surname), with the given name typically assigned at birth and the surname inherited through the paternal, maternal, or dual lineage, depending on local custom.

The arts and architecture

The artistic and architectural traditions of humanity in the 28th century remain rooted in centuries-old principles, mediums, and aesthetic sensibilities.

Religion and spirituality

Religion and spirituality remain enduring and deeply embedded elements of human culture throughout the 28th century, with persistent adherence across both Earth and her colonies.

Society

Human society in the 28th century retains its foundational structure, values, and rhythms largely unchanged from earlier centuries.

Gender

In the 28th century, the dominant understanding of gender has returned to a more traditional and biologically grounded perspective.

Ethnicity

Ethnicity among humans is massive compared to other races. Humans not only divide themselves into hundreds of historical and modern ethnic groups, but numerous other colonial ethnic groups also spared across human-controlled space.

Government and politics

Human governance is difficult, as there are many forms of government on both Earth and throughout her colonies.

Relations with Other Races

Humanity, despite having colonized near 300 planets, moons, and asteroids, has made "first contact" with any other races. However, they have certain protocols in place for such an event. One of which is the Colonial First Contact Act, a document authered by US president Scott R. Hunt, and adopted by all UNF member nation in 2053. The act outlines humanity's response to alien contact, both friendly and hostile. In the near 700 hundred year since the act has been in effect, it has not been enacted upon.
