Zemblis is the name for the technologically advanced planet within our (solar system/galaxy).
Inhabited by humans and aliens alike, the planet has been prospering for centuries. The planet is old, many many millions of years old, but there has been life (and signs of life) for as far back as can be recorded. The planet was originally human in origin, but when alien species colonised they brought with them technology that advanced the planet faster than anyone could have expected. Naturally wars were fought during these first colonisation efforts, adn the human's proved their worth time and time again before being assimilated and accepted as a part of the galaxy.
Historically, records only exist a short while before the alien races first visited, as Zemblis was torn by decade long wars. Mankind had been raised so far upon their own technological achievements, only to turn them in on themselves to cause destruction. The arrival of other races united the humans, but led to more fighting and more death.
Eventually a peace treaty was signed, and Zemblis has now become a major trade stop-off destination for all of the universe. Humankind has benifited from this attention, and the planet resembles a futuristic fantasy world. The cities are compromised of tall, gleaming towers and large spaceports with millions of inhabitants of many races.
Zemblis is temperate all year round, as even the weather is able to be controlled with technology.
