I. The Nature of Power The Agrospectrum
Every living being hums with an unseen vibration an Echo.
The ancients named this resonance Agro, the harmony between Body, Spirit, and Motion.
Centuries of cultivation gave birth to Agrospectrum Theory the study of how emotion, intent, and physical movement could shape the invisible pulse of the soul. This discovery became the foundation of all martial civilization.
Essence Law:
"Every motion contains memory. Every memory becomes sound.
When that sound can shatter stone, you are no longer human you are Agro."
II. The Power Hierarchy
Tier Title Description
1. Mortal Stage Ordinary human. Possesses dormant echo.
2. Pulse Initiate First awakening of inner echo; gains speed, stamina, and perception boosts.
3. Agro User Can channel echo through attacks; basic energy projection.
4. Echo Adept Externalizes echo; attacks leave visible trails or afterimages.
5. Spectrum Walker Begins blending multiple echoes into hybrid styles; foundation of individuality.
6. Domain Sayer Projects their internal echo outward, altering the battlefield's physics.
7. Saint Class Echo becomes concept; a strike can erase lesser echoes from existence.
8. Agro Saint Transcendent mortals who rewrite the laws of movement and impact.
9. Trojan Star Masters who command celestial echoes; can warp cause and effect itself.
10. Void Singularity (Mythic) Theoretical limit. A being whose echo silences all creation.
Each Saint leaves behind Saint Relics objects still vibrating with their final resonance. These relics can awaken or corrupt anyone who dares to listen.
III. The Copy Saint Reto Kopi
Reto Kopi was born in Cradle Continent's lowest district, where echoes are weak and dreams are weaker. His parents were martial artisans fighters who studied sound and motion but never reached true resonance.
At fifteen, Reto's latent ability manifested during a street brawl. He instinctively mirrored an opponent's strike after seeing it once faster, stronger, cleaner. What he copied was not merely technique, but Echo itself.
The Kopi Instinct
• Core Ability: Copy any physical, martial, or echo based action seen.
• Initial Limit: Copies at 0.001% potency.
• Bass Boost: Each repetition amplifies the copy ×1000 until synchronization is complete.
• Restrictions:
• Cannot copy "Uncopyable" echoes (divine bloodlines, saint domains, cursed styles).
• Unstable echoes can fragment Reto's mind some evolve their own will inside him.
• Overuse causes "Echo Feedback" where Reto's copied frequencies clash violently.
His destiny will challenge the very laws of originality:
Can one who imitates the world ever become something greater than it?
IV. The World of Echos
The world of Aetherion is divided into four primary continents and an orbital plane called the Astral Rift.
1. Cradle Continent
"The womb of echoes."
Birthplace of martial civilization. Divided between Guild Cities and lawless echo zones. Here, Reto's journey begins.
2. Verdan Frontier
"The land of beasts that learned to speak through motion."
Home to creatures whose echoes evolved naturally. Many early Agro techniques were stolen from their rhythms.
3. Heiros Dominion
"The empire of Saints."
Governed by noble families possessing uncopyable bloodline echoes. Their hierarchy forms the world's political center.
4. Astral Riftlands
"Where echoes become stars."
A shattered continent where gravity itself responds to martial resonance. The Trojan Stars originated here.
5. The Upper Plane: Echo Veil
Said to be a reflection of the mortal world a dimensional archive of every sound ever made. Few return from it sane.
V. Careers and Guild Tracks
Every practitioner aligns under a guild to survive and cultivate resources.
Track Focus Function
Duelist Combat specialists Compete in ranked arenas; fame and fortune.
Path Seeker Wanderers Pursue lost styles and evolve new echoes.
Echoforger Craftsmen Create weapons tuned to specific frequencies.
Saint Scholar Researchers Study echo theory, bloodlines, and relic corruption.
City Guardian Defenders Maintain echo barriers protecting cities from resonance storms.
VI. The World's Backstory "The First Resonance"
Long before the rise of Cradle's empires, the world was silent. Then came The First Resonance, when the heavens split and a sound unlike any other rang across creation. That vibration birthed the first life and became the origin of all echoes.
The Trojan Stars, twelve beings who mastered the First Resonance, discovered that echoes could bend not only matter, but fate itself. Their war the Agrofall Conflict nearly collapsed reality.
When the final Trojan vanished, their echoes seeded the bloodlines of the Saint Families.
Since then, all cultivation, all war, and all progress have been echoes of those ancient twelve.
VII. The Modern Era "The Age of Forgers"
The current age is defined by two words: Creation and Imitation.
New martial arts evolve daily. For every innovator, there are ten imitators trying to perfect what already exists.
But somewhere in the Cradle's alleys, a young man named Reto Kopi is about to blur that line completely. His existence may reignite the war that the Trojans ended millennia ago.
Because if imitation becomes flawless
then even the gods will fear being copied.
