Alterra is one of the largest suppliers of space technology and consumer electronics in the galactic federation. It is an official supplier of the Transsystem Federation (TSF). It was Alterra that financed the mission of the ship Aurora, which reached planet 4546B through a phase gate. The Aurora was sent to this planet with two main missions: to establish a phase gate in the Ariadne Arm to expand the corporation's influence in the galaxy, and to locate survivors from the mining ship Degasi, which disappeared 10 years ago.

Around a thousand years ago, a race of cybernetic beings codenamed "Architects" introduced a "green" strain of the Kharaa bacteria to the planet's surface in search of a neutralizing agent. Despite the technological advances and scientific achievements of the Architects, who had established numerous complexes and installations in both ecosystems, the synthesis of a cure was never completed due to an incident involving an enraged Sea Dragon Leviathan, whose egg was stolen by the leader of the alien mission, attacking the Disease Research Center and releasing the bacteria into the open waters, leading to a mass extinction. Among the surviving species, with numerous unexplained or rudimentary adaptations, were only representatives of fauna adapted to sustaining the "Sea Emperor" specimen and absorbing its enzyme, which was distributed by squeakers through the alien pipeline network. Since that time, the celestial body has been under planetary quarantine, reinforced by a security quarantine platform and guards at the global and local levels, respectively.
Haraa is spread through water and when healthy creatures eat infected ones.
After entering the body, the disease remains dormant for a period of time, after which green cysts begin to appear on the victim's skin. Initially, they are small and ungrouped, but as the infection spreads throughout the body, they increase in size and form clusters.
Other early symptoms of Haraa infection are somewhat similar to those of influenza (unique ones include itching and skin irritation). In later stages, the disease causes immunodeficiency, DNA damage, and tumor formation. One CCP report also mentions increased aggressiveness in infected animals.
The Quarantine Weapon was built by an alien race about a thousand years ago to prevent the spread of the Kharaa bacteria. It was programmed to destroy all spacecraft attempting to enter or exit the planet's atmosphere. Power to the Anti-Aircraft Defense is fed through cables from the Alien Thermal Power Plant and concentrated in the Energy Core. The Anti-Aircraft Defense's power supply, or in other words, the Weapon, can be shut down via the Anti-Aircraft Defense System Shutdown Terminal. However, only a being uninfected by Kharaa can perform this.

4546b is a category III ocean planet, almost entirely covered in water. It is smaller than Earth. Its atmosphere is breathable, composed of acidic nitrogen. It is located in the Ariadne Arm, orbiting the star 4546. A day lasts 20 minutes (the day-to-night ratio is 3:1). The planet has two moons, one of which is very close, causing frequent solar eclipses.
The planet contains a variety of ecosystems: safe shallows, kelp forests, grassy plateaus, underwater islands, a mushroom forest, the Authors' crash site, the Kush zone, floating islands, a large reef, a rare reef, blood kelp, sand dunes, and an inactive lava zone. The planet is also teeming with fauna: from small, harmless fish to enormous, predatory Leviathans. The planet is also rich in minerals, such as shale, silver, gold, platinum, magnetite, and much more.

Curly - Jimmy.
Curly and Jimmy were longtime friends who later went their separate ways. But a few years later, they met again. While Curly was working at the Pony Express, Jimmy was having financial problems. Wanting to help, Curly offered Jimmy a job at the Pony Express, which Jimmy accepted. Jimmy quickly rose through the ranks, likely thanks to Curly. Curly genuinely cares for his friend and, despite his bad temper, tries to help him improve his relationships with the other crew members. Jimmy, while respectful, is also envious. He believes he should be the captain of the plane, even though he doesn't fully understand the responsibility involved.
Curly - Anya.
Curly cares for Anya as a member of his crew, and Anya respects the captain and trusts him enough to tell him about things that are bothering her.
Curly - Swansea.
Their relationship is a standard captain-subordinate relationship. Curly trusts Swansea to do his job, and Swansea respects Curly.
Curly - Daisuke.
They don't interact with each other very often. But Curly values ​​him as part of his crew, and Daisuke respects his captain.
Jimmy - Anya.
Jimmy doesn't clash with Anya, but he considers her medical skills mediocre, despite her excellent nursing skills. Anya, however, tries to find common ground with him. (In this story, Jimmy didn't rape Anya, so their relationship is neutral.)
Jimmy - Swansea.
They treat each other without open hostility, although they dislike each other because of their bad characters.
Jimmy - Daisuke.
They rarely interact with each other. But Jimmy doesn't take the guy seriously and thinks he's just getting in the way.
Anya - Swansea.
They have a friendly relationship. They trust each other.
Anya - Daisuke.
They are friends and often spend their free time playing board games together.
Swansea - Daisuke.
Daisuke's overenthusiasm somewhat irritates Swansea. However, Swansea truly views his intern as a son or ward. He worries about him and wants to make sure he's safe. He believes Daisuke is a good guy and deserves a good life.

Daisuke is a trainee on the space freighter Tulpar, serving under the ship's mechanic, Swansea. He is approximately 20 years old. Daisuke is a tall young man with a tanned complexion, medium-length, partly dyed brown hair, and almond-shaped brown eyes. He has a round face with one mole on each cheek, with the right mole located under his eye and the left slightly below. He wears a yellow and red Pony Express T-shirt, a pink button-down shirt with a hibiscus pattern, blue jeans, and black boots.
A key trait of Daisuke's is his optimism. As a trainee, Daisuke is eager to be useful and earn praise and recognition from his senior crew members. He genuinely cares for his comrades and wants to help them and maintain a positive atmosphere within the crew. Daisuke is also characterized by his trusting and naive nature. He is accustomed to seeing the good in people and rarely suspects others of ill intentions, which is why he easily becomes attached to his crewmates and trusts them wholeheartedly.
His parents forced him to work at Pony Express, as Daisuke had previously led a dissolute life and had shown little ambition. A serious job away from home was supposed to instill responsibility in the young man. At first, Daisuke wasn't thrilled about the internship, but he eventually accepted it and put on a masculine facade.

Swansea is the engineer on the cargo ship Tulpar, responsible for the ship's maintenance and ensuring all systems are in good working order. He is approximately 40 years old. Swansea is tall with short brown hair and blue eyes. He has a noticeable belly, likely due to his age and a past history of alcoholism. He is often depicted with a frown. He wears a yellow and red Pony Express polo shirt, a pair of jeans, and white and blue sneakers.
At first glance, Swansea seems like an ordinary, grumpy man, and one gets the sense that he's constantly dissatisfied. However, he's willing to fight for those he cares about and is willing to sacrifice himself.
He was an alcoholic in his youth, but one day, waking up in a ditch after drinking, he decided to change his life. He quit drinking, got married, and had children. He had a happy life on earth. But something was missing. He decided to get a job as a mechanic on the Pony Express. That's how he ended up on Curly's crew, where he was later assigned Daisuke as an intern.

Anya is a nurse on Tulpar. She works in the infirmary, conducting psychological evaluations for crew members and treating them. She is approximately 27 years old. She has black, slightly tousled, shoulder-length hair and black eyes. She wears a Pony Express jumpsuit over a pink, green, and white striped turtleneck. She wears a pair of brown sandals with white socks. Her downcast eyes, prominent eyelashes, and slight lack of sleep give her a sad appearance.
Anya is a kind, intelligent, sensitive, and goal-oriented girl with a passion for nursing and a great sense of humor. Despite applying to medical school eight times and failing, she continues to apply, demonstrating her love and dedication to medicine. After failing to get into college, Anya took a job at Pony Express, as they offer nursing training. This led to her joining Curly's team. Anya strives to see the good in people and finds it easy to connect with others. In her free time, she pursues self-improvement by studying books on psychology and medicine.

Jimmy is the second pilot of the cargo ship Tulpara. He is about 40 years old. In the event of an emergency, he is expected to assume the role of captain. He has straight brown hair parted in the middle of his head, brown eyes, and a light stubble on his face. He wears blue Pony Express overalls over a white long-sleeved shirt and black sneakers.
Jimmy was having difficulties on Earth. To resolve them, Jimmy, out of old friendship, offered him a job on the Pony Express. Thus, they found themselves on the same team. But despite his help with the job, Jimmy feels not only respect for Curly but also envy. He believes he should have been captain, not Curly, though he doesn't say it out loud. He wants to return to Earth. In conversation, he comes across as irritable and impulsive, prone to sharp emotional reactions. Jimmy loses his temper easily, is sensitive to pressure, and often responds to stress with outbursts of anger or caustic remarks. However, behind this behavior lies not confidence, but a deep inner instability and an inability to cope with his emotions.

Curly is the captain of the cargo ship Tulpar and is responsible for navigation. He is approximately 40 years old. Curly has a medium build, blue eyes, and light, slightly curled hair. He wears blue Pony Express overalls over a yellow and red T-shirt.
Curly's primary character trait is a genuine concern for people. As captain, he treats every crew member with respect and understanding, avoiding an authoritarian management style. Instead of strict discipline, he prefers to build relationships based on trust, viewing his subordinates as comrades rather than mere employees. He is attentive to their moods, strives to smooth over conflicts, and maintains a friendly atmosphere even during long space flights. Curly also has a strong sense of responsibility. He takes his responsibilities seriously and genuinely cares for the crew's safety. At the same time, Curly tends to see the good in people. This trait is especially evident in his attitude toward Jimmy. Curly's most controversial personality trait is his indecisiveness. When faced with a difficult moral dilemma, he is unable to make the necessary decision quickly. Nevertheless, Curly is very courageous and is willing to sacrifice his life for his crewmates. An important characteristic of Curly's personality is his willingness to take responsibility. He believes he has a responsibility to resolve the crew's problems independently, even if it requires personal sacrifice. At the same time, the captain rarely demands anything of others and tries not to shift his own difficulties onto them. This approach makes him a good leader, but it also prevents him from recognizing when some situations require more drastic measures. His desire to maintain peace and mutual understanding sometimes outweighs the need to act decisively. Curly also possesses a strong sense of empathy. He understands the feelings of others well and genuinely cares for the crew.
