Zoids: The Western Continent War
• Zi was originally the closest planet to its sun, but is now the second closest.
• Zi’s sun is an F-class yellow-white star.
• Zi’s average orbital speed is 62,964 km/h.
• Zi’s diameter is 6230.2 miles.
• Zi’s axial tilt is 26.3°.
• Zi and its solar system were formed roughly 5 billion years ago.
• 200 million years after formation, the heavy Planet Mi (1/4 of Zi’s diameter) collided with Zi, becoming part of the planet and blowing 1/4 of its crust into space.
• 78% of the heavy metals on Zi are thought to originate from Mi.
• Fragments from Mi and crust from Zi became three moons: “De”, “Se” and “Ae”.
• “De”, the yellow moon, is the smallest moon and the closest to Zi. De is only 111,852 miles from Zi and getting closer every day. [De was destroyed by the comet Thorne in ZAC 2056.]
• “Se”, the middle moon, is blue, and “Ae” (the largest and most distant) is red. Due to its mass, Ae has a highly eccentric and inclined orbit. Ae is thought to be composed entirely of fragments from Mi’s moon “Te”.
• 700,000 years ago, a group of 8 tiny planetoids crashed into Zi’s equator, causing the current geography. The largest had a 10.1 mile radius and was estimated to weigh 1.01312 trillion tons.
• Zi currently has 6 major continents (Northern, Southern, Eastern, Western, Central and Dark).
Planet Zi is home to two dominant types of life: Zoidians and Zoids.
Zoidians were originally lifeforms very similar to humans. Most of the original Zoidians were wiped out by the impact of shards of De in ZAC 2056. Zi has since been repopulated by the remaining Zoidians intermarrying with the survivors of the crew of the Globally III spacecraft from Earth which crashed on Zi in ZAC 2029.
Zoids are metallic lifeforms that have evolved on Zi due to the heavy metallic and magnetic nature of the planet. Naturally-occurring wild Zoids are complete organisms, subsisting off of minerals or magnetic nutrition. Carnivorous types of wild Zoids will feast on the cores of other Zoids.
Combat Zoids are created by removing the cores from naturally occurring Zoids and placing them into an artificial body, and attaching control mechanisms to the core.
Magnetic currents are more prevalent than winds on Zi, due to the heavy concentrations of metals in its crust, so most flying Zoids use magnetic resonance to produce lift, rather than the downdraft used by conventional aircraft on Earth. However, this means their wings tend to be more susceptible to damage.
