Zchol

Zchol was the fourth planet in the Sidianial-system in the Botchok Planetary Congress. It was the only class-M planet in its system, and it had no moons. It was home to an Orion colony.

History
Five major races have all called Zchol their ancestral home at one time or another, each conquered by the next. After the original inhabitants, the Athan invaded and brought in a small number of Orion slaves. The Athan were in turn conquered by the Shani, who were similarly conquered by the Kezt. The Orion slaves survived each invasion, and were dominated by all three races, but steadily grew in number.

The Kezt were members of the Nine Worlds Confederation, founded circa 700 BCE (that is, 800 years after 1508 BCE). The Nine Worlds sought to limit Orion freedoms and have greater controls over the slaves. When the Orion War for their liberation broke out between 94 to 56 BCE, the Orion slaves rebelled. They sabotaged the Nine Worlds Confederation war effort, kept their ground forces occupied and hindered their space efforts, no matter the risk to themselves. Zchol suffered particularly heavy fighting in a conflict known as the Agony of Zchol.

With the conclusion of the war and the golden age of the New Days, Zchol rebuilt, but it was never able to heal all the scars left by the Agony. Then the Reverse came, bringing with it the century-long Purge, in which Zchol's multiracial population was decimated and many fled. Though trade was cut-off and the population reduced, the Orions of Zchol were now free of outside interference.

Looking inward, they healed their social ills and developed the world and its resources. Finally, Zchol had become a model Orion Colony, peaceful and prosperous with a population of 3.1 billion people. The Zchol Planetary Congress (modeled on the Botchok Planetary Congress governed the world).

The planet was conquered in 2153 during the  Borderland Blitz, the  Klingon Empire   annexation of the  Botchok Planetary Congress , becoming a protectorate world when the Orion government surrendered.

Enviroment
Zchol had a cool temperate climate, a class-M terrestrial atmosphere and a 23-hour-long day. It had a total surface area of 648,729,120 square kilometers and, with 30% land mass, a total land area of 194,618,730 square kilometers. About 42% of its makeup was normal metals, 23% was radioactive elements, 15% was gemstones, 9% was industrial crystals, and 5% was special minerals.
