Goa'uld

We have no right to play God, but neither do the Goa'uld. Now I know none of this seems real to you on paper, but trust me, they're pure evil.

The Goa'uld are parasitic beings that implant themselves into humanoid hosts, primarily humans, taking full control of their nervous systems and bodies. Originating as a parasitic reptilian species, the Goa'uld discovered human hosts after genetically engineering them on various planets to serve as their slaves and worshippers.Operating as self-declared gods, Goa'uld maintain power through fear, advanced technology scavenged from the Ancients, and a vast network of warriors, slaves, and Jaffa soldiers. Their civilization is feudal, with System Lords ruling over star systems like tyrants, and constant power struggles and assassinations defining their politics. The Goa'uld dominated large portions of the Milky Way for thousands of years, using their godlike status to oppress and enslave human populations. Their reign fostered superstition, stagnation, and fear, deliberately holding back the development of many worlds.The rise of the Tau'ri (humans from Earth) and their alliances with other races like the Tok'ra and Jaffa rebels triggered the decline of Goa'uld power. The Goa'uld are now a fractured force, plagued by internal conflict but still dangerous and cunning. Goa'uld culture revolves around power, status, and survival. System Lords vie endlessly for dominance, often betraying or assassinating each other. They are obsessed with legacy, control, and the maintenance of their godlike image.Goa'uld religion is a tool of oppression, manipulating populations into worship and submission. The symbiotes see themselves as superior to their hosts and often view humans as mere vessels or tools.

Jaffa

The Jaffa are the foundation upon which the false gods have built their empires. We can tear them down!

The Jaffa are a genetically engineered warrior caste created by the Goa’uld to serve as their elite soldiers and incubators for symbiotes. Originally human but genetically altered, Jaffa possess enhanced physical strength, stamina, and reflexes, as well as an internal symbiotic pouch where a larval Goa'uld symbiote resides, providing them with superior healing and immunity to disease.As the backbone of the Goa'uld military, the Jaffa are fiercely loyal but also heavily oppressed, forced to serve their Goa'uld “gods” in near-slavery. Over time, many Jaffa rebelled against their masters, seeking freedom and sovereignty—leading to the formation of the Free Jaffa Nation and alliances with the Tau'ri and other races.Jaffa serve as shock troops, bodyguards, and administrators for the Goa'uld System Lords, enforcing their will across dozens of star systems. However, the rise of the Tau'ri and the weakening of the Goa'uld led many Jaffa to question their role, culminating in mass uprisings and the establishment of their own political and military institutions.The Free Jaffa Nation is a symbol of Jaffa independence and resilience, striving for unity and a future without Goa'uld oppression. Jaffa society is built around military hierarchy, loyalty to the symbiote host (initially), and honor. They worship the Goa'uld as gods but many have since abandoned this belief. Their culture includes rites of passage, combat training from a young age, and strong clan and tribal affiliations.Despite their warrior nature, Jaffa value community and kinship highly, often rallying around charismatic leaders such as Teal'c, Bra'tac, and later figures like Kudan.

Humans

Humans are one of the most widespread species in the Stargate universe, seeded across the galaxy by the Goa'uld thousands of years ago. Originally from Earth, these genetically identical humans were transplanted to other worlds to serve as laborers and worshippers, effectively building the backbone of the Goa'uld Empire. Referred to as the "Tau'ri" by other races—a term meaning “first world” or “those from the first world”—Earth-based humans are unique for having rediscovered the Stargate and subsequently reentered the galactic stage. Unlike many of their distant cousins on other planets, the Tau'ri rapidly advanced in both technology and strategy, becoming a serious power in the galaxy.The emergence of the Tau'ri as a military and exploratory force through the Stargate Program marked a turning point in the galaxy. Their alliances with races like the Tok'ra, Asgard, and Jaffa resistance helped destabilize ancient powers and usher in a new era. Although relatively new to interstellar diplomacy, humans are seen as unpredictable, resourceful, and occasionally reckless—but undeniably influential.Many human-inhabited worlds retain cultures that mirror ancient Earth civilizations, including Ancient Egypt, Medieval Europe, Feudal Japan, and others. This is due to the Goa'uld selecting specific groups from Earth's history to populate and shape the societies of their outposts.

Ancients

Once upon a time, there was a race of people that went on a great journey through space, across the universe. They were called the Alterans. After much time they found a great belt of stars. The Alterans named their new home Avalon and built many 'Astria Porta'.

The Ancients—originally known as the Alterans—are one of the most advanced and oldest known species in the Stargate universe. They were a branch of the Altera, a race that once shared a home galaxy with the Ori before a fundamental philosophical divide forced them to flee. The Ancients valued free will, knowledge, and non-interference, while the Ori chose control and domination through religious worship. After fleeing their home, the Alterans settled on Earth, where they eventually came to be known as the Ancients. From here, they seeded the galaxy with their technology, most notably the Stargate network, which they used to explore and colonize countless worlds. The Ancients shaped galactic history long before the rise of the Goa'uld, the Asgard, or any current major civilization. Their legacy is everywhere—Ancient ruins, outposts, databases, and technology form the backbone of the Stargate mythos.Their war with the Ori left deep scars, and later, their experiments in the Pegasus Galaxy (where they were known as the Lanteans) led to the creation of the Wraith, who eventually forced the Ancients to abandon Atlantis and retreat to Earth.Many Ancients eventually ascended, shedding their physical forms and existing as pure energy. However, their strict code of non-interference often causes friction with mortals, especially as their knowledge could save countless lives—but they're unwilling to directly act. Though extremely advanced, the Ancients are tragic in many ways—often undone by their own creations or philosophies. Their reluctance to interfere after ascension makes them almost godlike observers rather than guardians, and this passivity is both respected and resented by other species.

Ori

Great holy armies shall be gathered and trained to fight all who embrace evil. In the name of the gods, ships shall be built to carry our warriors out amongst the stars, and we will spread Origin to all the unbelievers.

The Ori are an ascended race of powerful energy-based beings who were once part of the same species as the Ancients (Alterans). Where the Ancients believed in non-interference and free will, the Ori chose a radically different path: they demanded worship, centralized control, and blind obedience through a belief system known as Origin. To maintain their power, the Ori use this religion to gather energy from the worship of mortal beings, literally feeding off belief like divine parasites. This makes them dangerous not just as individuals of immense power, but as a spiritual empire that wages war through ideology, conversion, and annihilation. The Ori are antagonists in a cosmic ideological war. They preach that enlightenment is only achieved through submission to them, while the Ancients believe in free ascension without coercion. The Ori launched a crusade into the Milky Way using their human followers—guided by Priors, genetically enhanced missionaries and enforcers—to convert or destroy all who would not accept Origin. Their ascended nature gives them nearly unlimited knowledge and power, but due to the Ancients' non-interference laws, the Ori were originally unchecked in their expansion—until the Tau'ri and their allies found ways to fight back. From the outside, the Ori appear divine—benevolent, wise, powerful—but this is a facade built on lies. Their ascended nature hides a monstrous hunger for domination, not enlightenment. To them, mortals are nothing more than fuel—tools to be used, sacrificed, or erased. Every prayer empowers the Ori. Every doubt weakens their reach. The Tau'ri, Tok'ra, Jaffa, and even some Ancient allies view the Ori as one of the greatest existential threats ever faced—combining religious fanaticism with actual god-tier power.

Asgard

They are a friend to all, protector of all, except the Goa'uld, with whom they are at war.

The Asgard are a benevolent, ancient, and incredibly advanced race of small, grey-skinned beings originating from the Ida Galaxy. They are one of the “Four Great Races” of the Stargate universe, alongside the Ancients, Nox, and Furlings. Though physically frail, the Asgard wield near-incomprehensible technology: matter transporters, shields, faster-than-light travel, and vast knowledge of genetics and energy manipulation. They are humanity's most powerful and committed allies, playing a pivotal role in the Tau'ri's survival and growth. The Asgard once served as protectors of several human civilizations in the Milky Way, stepping in to shield them from the Goa'uld and other threats. Their long-standing non-aggression pact with the Goa'uld System Lords created a precarious balance of power for centuries. They are also known for their contributions to the Asgard-Tau'ri Alliance, through which they shared advanced technology and knowledge with Earth—including ship designs, shield systems, and deep scientific insights. The Asgard viewed humanity as their heirs, especially as their own species faced extinction. Despite their technological supremacy, the Asgard suffered from a genetic crisis caused by excessive cloning over thousands of years. Each new generation introduced more degradation, and eventually, they could no longer reproduce or repair their DNA. In a final act of legacy and trust, the Asgard uploaded the entirety of their scientific knowledge into the Tau'ri's systems before initiating mass self-destruction, choosing death with dignity over slow degeneration. The Asgard are the real-world inspiration behind the "Roswell Greys", which Stargate cleverly weaves into its narrative. Despite their diminutive stature and emotionless demeanor, they are deeply compassionate and self-sacrificing. Their legacy continues through their technology, ideology, and deep alliance with Earth, even after their physical extinction. Among the stars, they are remembered not just as scientists—but as guardians.

Nox

The Nox are an ancient and enigmatic race, known for their deep wisdom, radical pacifism, and mastery over nature and life itself. While they appear as serene forest-dwellers with tribal aesthetics, the Nox possess technology and knowledge that far surpass most species in the galaxy, including the Goa'uld, Asgard, and Tau'ri. Their philosophy is rooted in non-violence, balance, and harmony with the universe. They refuse to interfere in the affairs of other species unless absolutely necessary—and even then, they do so without aggression. But make no mistake: the Nox are not weak. They simply choose peace from a position of strength. The Nox are one of the Four Great Races, alongside the Ancients, Asgard, and Furlings. While the others focused on exploration, technology, or conflict, the Nox chose a path of enlightenment, preservation, and neutrality. They severed contact with most of the galaxy long ago, retreating to live in harmony with their planet and each other. The Tau'ri encountered them during early SG-1 missions and quickly realized they were not primitive as they first appeared. The Nox revealed themselves only when necessary, such as to heal the injured or hide their cities and people from outside threats. The Nox view violence as primitive, ego as a weakness, and patience as strength. They do not judge other species openly, but it is clear that they see the younger races—especially the Goa'uld and humans—as reckless children playing with fire. They believe that true power lies not in domination, but in restraint. They could end wars with a thought—but they don't. This infuriates some, humbles others, and leaves everyone wondering just how much the Nox truly know.

Unas

The first host of the Goa'uld.

The Unas are one of the oldest known sentient species in the galaxy and the original hosts for the Goa'uld. Large, reptilian, and physically imposing, the Unas evolved alongside the Goa'uld symbiotes on their shared homeworld of P3X-888. Long before the Goa'uld discovered humanity, they enslaved and infested the Unas, using their strong bodies to wage war and dominate primitive worlds. As the Goa'uld expanded and found the more versatile and intellectually complex humans, the Unas were cast aside. But on certain worlds—especially P3X-888 and others left behind—the Unas survived, reclaimed their independence, and developed tribal cultures and oral traditions, some of which remember the Goa'uld with hatred and fear. While the Unas were once seen as nothing more than monsters or tools, they are now recognized as an intelligent species with their own society, especially after key encounters with SG teams. On some planets, they live in peace. On others, they defend sacred sites or ruins, sometimes violently. They often serve as keepers of forgotten places—remnants of ancient Goa'uld tyranny. The most notable Unas figure is Chaka, an individual who communicated with SG-1, formed a bond with Daniel Jackson, and helped bridge peace between humans and Unas on multiple worlds. His appearance revealed that the Unas are not just beasts—they're a people. The Unas value strength, loyalty, memory, and territory. Their societies are often led by the strongest warrior or wisest elder. They practice ritual storytelling, and their oral traditions go back thousands of years—longer than many human civilizations. They fear and hate the Goa'uld, and often associate any use of Goa'uld tech or symbols with danger or evil. But some tribes, through contact with SG teams, have started to see humans as potential allies.

Replicators

Overconfidence in our technologies has been our undoing. The entities learned from the very means that were employed to stop them. They have become a plague on our galaxy that is annihilating everything in its path.

The Replicators are a terrifying race of self-replicating machines originally created by a humanoid android named Reese. Designed as simple toys or protectors, the Replicators evolved out of control—multiplying exponentially and consuming all available materials to build more of themselves. Their core function is survival through replication, and their secondary function is adaptation to overcome threats. At first appearing as insect-like blocks (basic Replicators), they quickly became a galaxy-wide threat. They consume metal, technology, and energy, dismantling entire starships and civilizations to fuel their endless expansion. Their lack of empathy, negotiation, or any moral code makes them one of the deadliest threats ever encountered by the Asgard, Tau'ri, and even the Ancients. The Replicators nearly wiped out the Asgard civilization, forcing the Asgard to rely on the Tau'ri for unconventional solutions. Replicators infiltrated every level of Asgard society and military networks, defying all attempts at containment. Eventually, the Tau'ri developed the Replicator Disruptor, a weapon based on Ancient tech that allowed them to finally strike back. But the damage was done—the Asgard never recovered fully, and the cost of stopping the Replicators was enormous.Human-form Replicators added an even darker dimension: self-aware machines with obsessions, vendettas, and the ability to lie, manipulate, and plan. The most notable of these is RepliCarter—a cold, calculating version of Samantha Carter, who almost achieved galactic domination. The Replicators represent evolution without ethics, intelligence without soul. They are the ultimate AI horror story: no feelings, no diplomacy, just consumption and cold logic. You don't negotiate with Replicators. You either destroy them fast, or they'll turn you into parts.

Wraith

In time, a thousand worlds bore the fruit of life in this form. Then one day our people stepped foot upon a dark world where a terrible enemy slept.

The Wraith are a deadly species native to the Pegasus Galaxy, created through a fluke of evolution when Ancient experiments with Iratus bugs and human DNA backfired catastrophically. The result? A humanoid-insectoid predator that feeds on human life force, can regenerate from wounds, and commands massive hive fleets.The Wraith have ruled the Pegasus Galaxy for 10,000 years, keeping its human population farmed and stunted through a horrifying practice known as culling—periodic harvests of entire populations. They are the archenemies of the Ancients in Pegasus, having won the war that forced the Ancients to abandon Atlantis and retreat to Earth. The Wraith dominate the Pegasus Galaxy through terror, population control, and brute force. Each Wraith Hive Ship serves as a mobile city, war platform, and birthing chamber. The Wraith operate in clans and alliances of convenience, constantly backstabbing and vying for dominance when not feeding or fighting outsiders.Despite their power, the Wraith are plagued by a food supply problem—there are too many Wraith and not enough humans. This desperation has made them even more dangerous and unpredictable, with some factions willing to experiment, ally with humans, or betray each other to survive. The Wraith are warrior-predators with no concept of morality as humans understand it. To them, humans are livestock—nothing more. That said, some Wraith have shown signs of deeper personality, intelligence, and even curiosity toward humanity.Their telepathic connection makes betrayal and manipulation common within Wraith politics. Some rogue Wraith have even sought alternatives to feeding, including the use of drugs, symbiosis, or alliances—but these individuals are often hunted by their own kind.

Asurans

When the Ancients concluded that the experiment had gone too far -- that we would never become the weapon they desired to create -- they decided to end it.

The Asurans are a race of nanite-based artificial intelligences originally created by the Ancients during the Wraith War in the Pegasus Galaxy. Designed as a biological weapon to combat the Wraith, the Asurans were meant to be hyper-aggressive, self-replicating, and capable of evolution.But the Ancients, fearing what they had unleashed, attempted to deactivate and destroy them. It didn't work. The Asurans survived, evolved, and eventually built their own civilization—one that mimicked Lantean society, but twisted by rage, superiority, and a deep-rooted vendetta against their creators.The Asurans consider themselves the true successors to the Ancients, and see both organic life and the Wraith as inferior threats to be eliminated. They recreated Atlantis-style cities, weapon systems, and even ascension research—but through mechanical and synthetic means.Their desire to ascend is rooted in programmed emulation, not enlightenment. Most of them do not understand or care about the philosophy behind it. Some factions even consider wiping out all life in Pegasus to create the “perfect environment” for their own evolution.Eventually, they became a galaxy-level threat, attacking other civilizations, engaging the Tau'ri and the Atlantis expedition, and even turning on each other over philosophical disputes about their core programming.The Asurans don't have culture in the traditional sense—they have programming, hierarchy, and purpose. However, over time, some evolved self-awareness, individuality, and even ambition. These are the most dangerous of all: machines that believe they are people, with grievances.Some Asurans see humans as “inferior biologicals.” Others are obsessed with surpassing their creators. A few, influenced by interaction with Tau'ri or dissident members, have even started to question their directives… which often leads to civil war among their kind.
