BRIEF HISTORY
HOW THE PLANET CAME TO BE?
In ancient times, the Helicon system had more than 3 planets, somewhere akin to 6+. As time went on, the outer planets collided with each other as well as space debris too. This created the asteroid field just beyond the 3rd planet, Eurthymia. Inside this field are hundreds of asteroids in varying sizes but only 9 of them would ever be colonized.
THE CITY
Kalliope only had 1 giant city underneath the dome with houses being made out of dark stone, floor-to-ceiling glass windows and colorful roofs. The population never passed the 9,000 mark before it was destroyed. They had no monarchy, only a council of elders with the Sailor Senshi getting a seat at the table when they were summoned.
THE ASTEROID
Kalliope was the 1st asteroid to be named and the 1st to see an ambitious colony of people from the planet Kharis settling on its harsh landscape. The Khari people used special domes to withstand the atmosphere and create their settlements. After a couple decades, more people from the other planets settled on Kalliope, mixing their bloodlines and created their own unique race of people. The same could be said for the other 7 asteroids colonized at the time.
CULTURE
THE PEOPLE
The Kalliopian people were said to be the masters of the arts, taking a specific interest in music and vocal performances. There used to be an old rumor that the Kalliopians were given their gift of music by the goddess of the universe herself. Being the pioneers of the arts gave them a bloodline ability that evolved into enhanced hearing. Kalliope influenced the other asteroid people to follow suit in their love for the arts and all of their Senshi reflect that too. Sailor Kalliope was the guardian of art and music.
The culture of this asteroid was built on music. There would be month-long festivals dedicated to music and everyone growing up here would learn at least 2 instruments. They even created their own instrument using a lyre and a flute. Poetry was also taught here.
THE DEMISE OF KALLIOPE
The demise of Kalliope were a mix of 3 things that sent the nation into almost extinction.
WAR & FAMINE
Shortly after Sailor Kalliope disappeared, the other asteroids took advantage of this and invaded. The Kalliopians fought hard for a couple months but it was no use. The other asteroids had Senshi backing them while they did not. This lead to half their population dying and the rest slow starving to death.
IMMIGRATION
Some of the Kalliopians flew their ships to other planets like Antheia or Kharis to get away from the war. They either assimilated to their new home or chose to live in solitude away from the general populace. Either way, today in the 21st century, there are no more true Kalliopian people who can keep the culture alive. There are people on other planets with heritage from Kalliope but it would be at least 2,000+ years of generations ago.
GALAXIA
In the 1980's-90's (Earth time), Sailor Galaxia was plowing through the Galaxy corrupted by power looking for Sailor Crystals. She happened to find the Helicon star system and went to town. Some of her followers recruited 2 asteroid senshi (Clio and Polymnia) while the other asteroids were destroyed; Kalliope included because their Senshi was missing. Galaxia and her followers also destroyed Kharis but couldn't take Antheia or Eurthymia so she stopped her assault and left the system alone.
