The Primus is the spiritual and philosophical leader of Nova Prime, the branch of the tripartite government that represents the spiritual dimension of society. His central philosophy is that the fall of Earth is proof that technology is a scourge, and humanity's survival depends on the deep spiritual bonds that unite all the inhabitants of Nova Prime.

Year 31 AE: Aboard the ark Exodus, Supreme Commander Raige relinquishes power under pressure from the Church and Reclamation movements. One year later, Rev. Salt is elected and formally creates the position of Primus.

Year 32 AE: The Rangers (who at that time were the militarized government) "invent" a religion aboard the arks, called Primus.

Year 67 AE: The Primus creates its own religious army and rewrites the rules so that the Primus leader is ruler indefinitely until death. Several remaining arks adopt the position.

Year 82 AE: The role of Primus (adopted from the Pegasus ark) is approved aboard the Asimov.

Year 95 AE: Primus Benjamin Gates (aboard the Exodus) introduces legislation to disband the Rangers as an individual unit and integrate all soldiers into the Primus Army.

Year 222 AE: A Primus leader begins to openly oppose science and industrialization on Nova Prime. After "much debate," the position of Savant is created as a counterweight.

Year 244 BCE: The Tripartite Pact is formed, institutionalizing joint government

1st – 3rd Quadrupeds, stout, with long, sharp claws. Dark, almost grayish skin. No visible eyes (blind).
4th Similar to the previous ones but thinner and faster; the right hind leg eliminated and thickened as a tail.
5th More slender and bouncy, with chromatophores that allow them to camouflage themselves (almost transparent layer).
6th (Ursa Maximus) The largest (~2.7–3 m), with a metallic carapace visible at the molecular level, venom in black globules in the mouth. It is the one that appears in the film.

1st generation: 576 BCE, 4 clawed limbs, blind, 100× superior sense of smell. 3 dozen released.

2nd generation: 651 AE Hollow bone structure (lighter and faster), extra joints, one hind leg removed and thickened (scorpion tail style). 3 dozen.

3rd generation: 726 AE They return to 4 legs + 2 arm-like appendages, sharper claws with keratin, first venom (paralyzing). 5 dozen.

4th generation: 801 AE Fear pheromone detection (the most lethal change). First reproductive capacity → objective: to make them permanent. 6 dozen in 2 waves.

5th generation: 876 AE Corrosive poison (burns flesh and bone), instant cellular digestion, faster and more agile, camouflage through chromatophores + transparent layer. 100 specimens.

6th generation (Ursa Maximus): 951 AE Metallic carapace at the molecular level (almost indestructible), venom in black globules that adhere to and pierce metal, imprints on specific targets, only 5 sleep periods of 1 hour, reproduce successfully and establish a permanent presence. 100 specimens.

Ghosting as a countermeasure
The only effective defense against a fear-sensing Ursa is Ghosting: a technique of completely suppressing the emotional response of fear, rendering the human invisible to the Ursa. Cypher Raige was the first living being to achieve this in 980 BCE; in the following two decades, only six more people demonstrated the ability, totaling seven Ghosts.

Ursas are genetically engineered creatures created by the S'Krell for a single purpose: to hunt and kill humans. They were first deployed on Nova Prime in 576 AE. They are blind beings that track their prey exclusively through the fear pheromones that humans release when they are afraid.

Capabilities:

Sense of smell 100 times more acute than that of humans; detects fear pheromones

A force superior to human capabilities in all generations

Speed: Outruns any human in a race; greater endurance

Venom: Oral glands that secrete black venom (varies by generation)

Carnivorous. Almost insatiable hunger; requires oxygen to metabolize.

Size: From ~2 m (gen. 1) to 2.7–3 m (gen. 6, Ursa Maximus)

Weight ~152 kg (gen. 6); surpasses the tallest human by at least 90 kg

Weaknesses

They only detect fear: if a human uses a sealed suit, enters battle rage or practices Ghosting (total fear suppression), the Ursa cannot locate him.

Susceptible to toxins: they have no natural resistance to external poisons.

Weak points in gen. 6: a small area on the back and a larger area on the belly, where the metallic shell does not protect.

Year 243 AE First attack: an S'Krell fleet appears above Nova Prime City. The Rangers repel it, but fusion weapons prove ineffective against its shields. Almost no technology survives for study.

Year 350 AE Second attack: robotic drones that fire and self-destruct. Prime Commander Esteban O'Hara is killed.

Year 576 AE Third attack: they release the first Ursa on the surface. From then on they avoid direct attacks.

Year 933 AE Unexpected and brutal direct attack against the main cities, very different from previous ones.

The S'Krell (also spelled "Skrel") are a mysterious and never-before-seen alien race that periodically attacks Nova Prime, a planet they consider a sacred land, although there is no record of them having inhabited it before the arrival of humans.

What is known (and what is not known)
No human has ever seen a S'Krell. Only their ships and robotic drones have been observed.
His real name is unknown. The term "Skrel" was coined by Carter Raige (an ancestor of Cypher), who, upon seeing the alien characters on the sides of their ships, noticed their similarity to letters of the English alphabet and used that name.
The Savant speculates that the S'Krell may lack optical organs, seeing the world in a way incomprehensible to humans.
It is unknown where they come from or what their exact objective is beyond eradicating humanity from Nova Prime.

Technology
Their ships are built with alloys unknown to humanity, suggesting a far superior level of development.
They possess energy shields that are highly resistant to human fusion-burst weapons.
Their technology is completely different from that of the race that accidentally granted humanity the Lightstream travel.
They possess remarkable interstellar efficiency: their ships have avoided the human satellite network for centuries.
They master large-scale genetic engineering: they created and continue to develop the Ursas, and it is believed that they have many more genetically engineered creatures that are still unknown to humanity.
Their ship designs changed very little between 243 BCE and 933 BCE, indicating enormous technological stability.

How the Cutlass works
The Cutlass is a double-bladed rope weapon with a central handle. Its operating principle is as follows:

Mechanism
The handle contains hundreds (or thousands, depending on the script) of extremely strong steel metal fibers.
By pressing rapid finger patterns on the handle, the fibers extend from both ends of the handle, forming leaves of different shapes and lengths.
The fibers operate using miniaturized magnetic fields that employ a principle called "quantum trapping" (based on the real-world phenomenon of flux pinning with superconductors). When activated, the fibers change shape to become one or two sheets of varying length and geometry.
Thanks to the enormous energy involved, the blades are self-repairing and self-sharpening: they never wear out.

Weakness
Because it relies on a controlled magnetic field, if used in the presence of a sufficiently powerful artificial magnetic field, the Cutlass may fail or not function as expected.

Models:

C-10: Weighs 2.5 kilograms and has 3 configurations (point, flat blade, hook) used by cadets as a tribute to the original FENIX system.

C-20: Weighs 3.3 kilograms and has 12 configurations (point, flat blade, sickle, hook, spade, etc.) used by Cypher to kill the first Ursa.

C-40: Weighs 4 kilograms and has 22 configurations (short blade, spear, long blade, sickle, dagger, etc.) Reserved for Prime Commander, field leaders or veterans.

C-50: Weighs 4.5 kilograms and has 23 configurations (All of the above plus a shield). It is still in testing.

Historical development
The core technologies were first used in 243 AE against the S'Krell.
The Cutlass as a weapon was formally developed in 576 AE in Lyla Kincaid's laboratories.
The reason the Rangers prefer close-quarters combat (without projectile weapons) is attributed to the influence of the Primus and their rejection of offensive technology, in addition to weighty considerations.

The Prime Commander is the supreme leader of the United Ranger Corps, and by extension, the military voice of Nova Prime's tripartite government. His central mission is "Preserving Humanity."

The current Prime Commander is Cypher Raige, described as "The greatest leader in the history of Nova Prime"

Operational details

Standard weapon: the Cutlass, a small, flexible, variable-configuration weapon, standard for the Mobile Rangers.

Tactics against Ursas: Squadrons of 8 Rangers must move in perfect formation; if one deviates, they all die.

Ghost Unit: a building within the Ranger Compound dedicated to training in the Ghosting technique, with two caged Ursas under custody who only come out during training.

Specialized Squads (created by Jason Raige after the first S'Krell attack):

Elite Response Squad — frontline defense against a new S'Krell attack.

Response and Recovery Squads — deployment in areas affected by attacks.

Historical context of the position
The position of Supreme Commander already existed on board the arks (the first was Skyler Raige II, in 2065 AD).
After arriving on Nova Prime and forming the Tripartite Pact (244 AE), the title evolved to Prime Commander as part of the ruling trio alongside the Primus and the Savant.
In 651 AE, after the second Ursa attack, the Primus, the Savant, and the Prime Commander were killed, and Vaness assumed command.

Pact structure:

Formed in 244 AE, the pact establishes that the three estates jointly govern Nova Prime: Prime Commander, Savant, and Primus. The fundamental rule is that without a balance between the three, society would collapse.

Context of its creation:

222 AE: The position of Savant is created after the Primus begins to oppose science.

243 AE: The conflict between followers of the Savant and the Primus escalates to "uncontrollable" levels; the S'Krell invade Nova Prime for the first time.

244 AE: In response to that crisis, the Tripartite Pact was formed to institutionalize joint government.

The Savant is the leader of Nova Prime's scientific community, a position created in 222 BCE after intense debate when Primus began to openly oppose science and industrialization. Its first occupant was Bree Kincaid.

Specific functions in daily life:

Oversight of all scientific activity: the Savant directs research, technological development, and innovation in general. It is the "practical" arm of the tripartite government.

Technological defense: After the S'Krell attacks, the Savant team analyzed the remains of the alien ships, identified the energy field generators (which blocked up to 80% of the fusion cannons) and developed the quantum entrapment weapons that turned the tide of the battle.

Biology and genetics: Biologists on the Savant determined that the Ursas were genetically engineered creatures designed to hunt humans. In fact, the name "Ursa" was chosen by a member of the Savant team after recalling the Latin name for the grizzly bear.

Surveillance infrastructure: Following the second S'Krell attack in 350 AE, the Savant Tak Kawasaki demanded the upgrade or replacement of the entire fleet of surveillance satellites, doubling their number.

Medicine and adaptation: the oxygen capsules that allow the humans of Nova Prime to breathe on Earth are a product of their scientific work.

Constant tension with the Primus
The relationship between the Savant and the Primus is inherently conflictive: while the Savant believes technology is the key to survival, the Primus sees it as the cause of Earth's downfall. By 243 BCE, the conflict between their followers had escalated to "uncontrollable" levels, contributing to the formation of the Tripartite Pact in 244 BCE, which established joint rule by Prime Commander, Savant, and Primus.

In practice, the Savant is the one who sustains all of Nova Prime's technological infrastructure: from spaceships and satellites to weapons and medicine.

Slightly larger than Earth, with less gravity.

60–70% of land surface and 30–40% of oceans (with frozen polar ice caps).

It is the fifth planet in its star system; it takes 300 days to orbit.

The year is divided into 10 months of 30 days each, named after a land country: America, Australia, Brazil, China, Egypt, Germany, Mexico, India, Great Britain and Russia

Nova Prime city is the human capital of Nova Prime.

Location and architecture:

It is located in the Falkor Desert, on the edge of a canyon.
The architecture is metallic, aerodynamic, and futuristic in appearance: oval structures made of glass and reflective surfaces, almost like terrestrial spaceships. The contrast with the surrounding red canyons is striking.
It houses the Nova Prime Air Station, the main takeoff and landing point for aircraft.
Society and government
Society is organized under a tripartite government (Ranger Corps, Primus, and Savant), which creates a constant tension between spiritualism (Primus, which rejects technology) and scientific advancement (Savant).
The population grew from 125,000 per ark to over 9,000 in just 203 AE, and continues to expand.
There is a military academy where young men train to join the Ranger Corps.

Constant threat:

Unlike a "normal" life, existence in Nova Prime City is marked by fear of the Ursas and attacks from the S'Krell.
In 997 AE there was a direct attack on the city that resulted in the "birth" of new Ghosts.
The areas near the city are restricted by the Rangers following Ursa's attacks.

Biological adaptation:

The humans of Nova Prime (Nova type) have adapted to the planet's lower gravity, becoming stronger and faster than the original Earthlings.
In return, they cannot breathe Earth's air without the help of oxygen capsules.

Culture
The calendar uses 10 months of 30 days, each named after a land country.
The technique of "Ghosting" (total suppression of fear) is a culturally valued skill, almost a combat and survival discipline.
The figure of the Ranger is a symbol of heroism and family legacy (the Raige family has been on the front line for a thousand years).

243 AE: First attack by the S'Krell, an alien species that considers Nova Prime their sacred land.

350 AE: Second S'Krell incursion.

576 AE: The S'Krell release the Ursa, a creature genetically engineered to hunt humans by detecting fear pheromones.
Cypher Raige discovers the technique of "Ghosting": suppressing fear completely to become invisible to the Ursas. Only 7 Ghosts exist.

951 AE: The sixth generation of Ursa arrives on Nova Prime; it is more lethal and can reproduce, establishing a permanent presence on the planet.

United Ranger Corps (Ranger): They are the military force for human order and peace. Soldiers specialized in combat with the mission of preserving and protecting human life.

The Primus: A philosophical/spiritual leader who rejects technological advancement, claiming it was the cause of the Earth's downfall.

The Savant: Promotes that science and technology are the key to human advancement and survival.

In the year 2025, humans built 10 space arks in response to environmental change on Earth. Each ark housed 125,000 humans, but of those 10 arks, only 6 were launched into space; therefore, only 750,000 living people reached space.

After 100 years of space travel at speeds exceeding that of light, the first human colonists arrived on Nova Prime and founded civilization.

After this, the human calendar changed from AD (After Christ) to using AE (After Earth), resetting the calendar to year 0.

By the year 100 AE, only 3 of the 6 space arks were still active.

On Earth, in the year 2025 AD, a great environmental cataclysm occurred. The Earth's core underwent a major change along with its magnetic field, generating gigantic environmental changes. Oxygen levels changed, becoming almost unbreathable for humans, so humans were forced to abandon Earth.
