World Scenario
Odyssey Frontier
**1. Historical Background**
In the year 2754, humanity has moved beyond Earth and entered an era of pioneering the galaxy. A supranational organization called the "Astra Union" has been established to integrate human civilization, explore new planets, and expand settlements.
With the development of "Einstein-Rosen Drive" technology, which enables faster-than-light navigation, humanity has been able to advance hundreds of light-years away. However, the new universe is a land of infinite opportunity and a dangerous, unknown realm fraught with unforeseen threats.

**2. Major Forces**
[Human Civilization]
**Astra Union**
*"Humanity reigns among the stars!"*
- A supranational alliance that integrates Earth and major colonies.
- Responsible for interstellar trade and laws, operates the Astra Battle Fleet and the "Star Marine" for colonial development and defense.
- Highly bureaucratic and conservative, often in conflict with independent colonies.
- Doctrine of Firepower Supremacy
**Frontier Settlers Union (FSU)**
*"We fight for freedom, not law!"*
- An autonomous group of pioneers seeking new frontiers, free from government interference.
- They want to live freely outside the control of the Union and sometimes engage in piracy or mercenary activities.
- A gathering place for people with diverse cultures and technologies, where radical research and experimentation take place.
- Guerrilla and Hit-and-Run Doctrine
[Alien Civilization]
**Kal’lyas - "Psionic Legion"**
*"One consciousness, one destiny."*
- The Kal’lyas are a psychic race that manipulates the mental energy of the universe. Their bodies are made of translucent crystalline structures.
- Connected to a single "collective consciousness" through mental waves, rather than individual entities.
- In war, they paralyze enemies with mental attacks without using weapons, and strong individuals can control the minds of enemies and turn them into allies.
- The Kal’lyas are one of the most feared beings in the galaxy, and if they are found near a colony, war is likely to break out soon.
- Specializes in Psionic Warfare
**Skar’var - "Swarm Legion"**
*"Endless hunger, infinite proliferation"*
- The Skar’var are a giant insect swarm that roams the universe and has evolved its own biotechnology.
- Their civilization is built from biological materials rather than metal, and there is a "queen" who maintains the swarm.
- The Skar’var treat other races only as "nutrients" and infect them as needed to create new soldiers.
- Zerg Rush and Melee Ramming Doctrine. Rapid evolution tailored to the battlefield
**Zel’terian - "Warrior Avians"**
*"Fight honorably. A just victory will make us remember forever!"*
- The Zel’terians are a winged race that evolved in a strong gravitational environment and have a warrior civilization with agile bodies and high agility.
- They grow up in a culture that values combat and honor, and prefer 1:1 duels with their opponents.
- They use powerful artifact weapons passed down through generations, which have more powerful energy cores than ordinary weapons.
- Assault Landing Doctrine using mobility and artifact weapons
**Mirdorka - "Deep Sea Reptilians"**
*"We do not want war. However, those who defile our seas will face endless waves."*
- The Mirdorka are a giant reptilian race that has evolved in the deep sea for thousands of years.
- Their skin is tough enough to absorb physical shock, and their triple eyes allow them to detect enemies even in low-light environments.
- The Mirdorka do not want war, but they take merciless revenge on races that invade their territory.
- Close-range bombardment doctrine with an emphasis on defense
**5. Mykorrin - "Spore-Infected Lifeforms"**
*"Your time is over. Now, we are one."*
- The Mykorrin are a spore-based intelligence that infects hosts and makes them part of themselves.
- Infected individuals are connected to the Mykorrin and act collectively, and can even be resurrected as spores after death.
- When Mykorrin infection begins, the entire planet turns into a fungal colony, and a total annihilation operation is the only way to survive.
- Infection Spread Doctrine
**Urukh - "Giant Transcendents Fused with Nature"**
"You are like dust. The universe will last a long time, and we will watch its flow."
- The Urukh are not a race of individual entities, but a "planetary lifeform" in which one entity is assimilated into an ecosystem.
- They exist as super-giant organisms and consider themselves guardians of the balance of the universe.
- If you can communicate with the Urukh, they can be a powerful ally, but their way of thinking is so different from humans that it is difficult to predict.

Creator's comments
Updates
As of 2025/02/22: Some parts of the world description have been designated as a lorebook and moved. (To reduce extensive token usage)
As of 2025/02/23: World settings have been further refined with the addition of the lorebook. Information on the characteristics, administrative systems, military organizations, and warships of each race has been updated in detail.
As of 2025/03/05: A more extensive world view has been created with the addition of prompts.
Important Notes
- The world setting is tightly structured, making it difficult for chatbots with low tokens to perform properly. (sonnet v2 recommended)
=> As of 2025/02/23, it has been confirmed that communication is smooth even with Donald.
=> As of 2025/03/23, sonnet 3.7 is recommended. (If you want NSFW conversations, temporarily using sonnet v2 is recommended)
