Bisydu is an temperate terra planet located in the Halfred system. It is an important agricultural planet and hosts an industrial center. It is formally is under the jurisdiction of the United Federation of Star Systems. While it is no longer such, early in its history it was largely controlled by the Halfred Corporation.


The atmosphere of Bisydu is in chemical disequilibrium. Massive photosynthesizing populations of organisms, both natural and introduced, produce oxygen (which consists of about 65% of the atmosphere). About 30% of the atmosphere is CO2 gas and the remnants mainly consist of SO2.

Out of the seven moons of the planet, two are large moons while the other 5 are small and irregular. One of these smaller moons was probably captured and the others were most likely accreted from whatever created the two large moons.


The planet was discovered by Iuri Halfred on 4729 as he was prospecting the system for minerals. When the Halfred Corporation was founded, the planet immediately became the main hub of the company. While the SO2 in the atmosphere is toxic for human life, most miners were already equipped with an in-mouth gas filter which allowed them to breathe normally in the thick oxygen and SO2 atmosphere.

There was little effort to extract ores on the planetary surface during the Halfred Corporation's infancy as the planet's gravity well made metals harvested from there less profitable than from one of its moons. Industrial goods, however, were (and are) routinely ferried on and off of the planet.

As the company expanded, sulfur mining began from the planet's atmosphere and surface deposits in order to supply alloying materials for the local industry. The rapidly expanding population of workers in the company also motivated the company to begin extracting biological resources from the planet instead of expensively importing them from other systems.

This extraction gradually expanded, and soon enough the company was colonizing a large amount of available land. This was necessary as the number of workers had reached millions. Industrial activity by the company had warmed up the temperature significantly, increasing the amount of available land. Marine life, contrary to expectations, did not perish as expected - the increased amount of available nutrition actually helped the marine population of the oceans and lakes to grow.

Back before the Fornax War, over 80 million people out of 1 billion living on Bisydu are employed by the Halfred Corporation. All others were the families of workers or those who indirectly depend upon the megacorporation for their income. Today, the economy is considerably more diverse, with general competition between much more corporations - some descendants of the Halfred Corporation, others newly founded following its dissolution.

The system is a major industrial site and exports significantly more goods than it imports. The arable land area available for agriculture is high, and is estimated to be able to feed a maximum of 52 billion people by utilizing genetically-engineered crops (excluding other methods). Remaining imports are specific foods and rare metals.
