## **Overview**

The **Osiris Colony**, also known as the **Osiris III Outpost** was a large-scale colony set up on the jovian moon of Callisto orbiting the prominent gas giant of Jupiter. Unlike other smaller colonies on other worlds such as Mars or Mercury, the Osiris Colony was fully self-sufficient, being able to generate it's own power and oxygen, grow it's own food and host five hundred colonists on board. To this day, the Osiris Colony remains the only colony situated on Callisto itself.

The Osiris Colony was established in 2073, as a part of the Osiris III mission of the Osiris Program, the first long-term habitation effort beyond Mars. One of the most major nations was created in the Osiris Colony during 2139, which has been named the Democratic Republic of Jovia. This nation would then go on to colonize the nearby moon of Ganymede, and began to return back to Earth, and start to restore it.

## **Layout**

The Osiris Colony consisted of many buildings designated to suit many roles. These ranged from central storage housing buildings to various solar farms.

The colony had a large, around twenty meters in height ring-sized central building designed to house the five hundred colonists on their stay on Callisto, named the habitation complex. The bottom level contained a retractable pad to lower the colonists to the surface of Callisto, and was large enough to contain a small-scaled rover inside it. The first half of the second floor was dedicated to storage of various science equipment, resources and such. The other half contained general habitation areas. The habitation complex had to be constantly spinning to reduce the effect of lower gravity on the colonists. The central area contained a single landing pad for a Skylone-class Shuttle, which was regularly used to explore the terrain of Callisto far more easily than with rovers.

Many spherical structures surrounded the colony, two of which had the same central purpose of storing water, spare parts and unmanned rovers to explore the terrain and submarines to explore the subglacial ocean of Callisto, which turned out to be entirely lifeless. One such storage structure contained a high amount of cryogenically frozen Human embryos and reproductive material, in case Earth would be engulfed in a global war, which eventually would happen. A fairly large science complex was considered the tallest building in the entire colony. This structure housed most of the science equipment, including various large scanners inside to detect organic signatures with a range of a hundred kilometers. The effect of this scanner only reached twenty kilometers inside the subglacial ocean. This essentially confirmed that multicellular lifeforms were unlikely to be present at such a height. The science quarters and most of the storage buildings had many smaller satellite dishes, that could focus on sending a single signal to to Earth.

A large scale solar farm consisting of around five hundred individual solar panels was present at a distance around a hundred meters outside of the colony, with a singular purpose of collecting energy for the colony to sustain itself and prosper.

## **History**

The Osiris Colony was originally constructed during the year of 2072 by 3D printers with simple artificial intelligence, using resources native to Callisto itself. This colony took around half a year to build, most of the time being used to extract the valuable minerals from Callisto.

The colony was briefly visited during the Grand Solarian Expedition, when the interplanetary spacecraft Adelia sent a small shuttle to land near the colony. This allowed both the inhabitants of Adelia and Osiris Colony to meet, and the colonists of Adelia could experience the otherwise alien lifestyle the inhabitants of Osiris Colony has to live.

During December 5th, 2139, the colony was struck by a large meteor around the size of it. This meteor, named the **Osiris Rock** actually fell near the colony itself, being redirected in orbit by a gravitational anomaly, only destroying half of the colony. Mission control reported the colony as entirely destroyed with next to chance of survivors. Since Callisto had no orbital satellites constructed around it at this point, a small satellite in orbit around Europa was redirected in orbit toward Callisto to see if the colony had any survivors. Any survivors weren't confirmed, as when the satellite reached a stable orbit around Callisto, the third world war had already broken out between the nations, engulfing all countries of planet Earth.

The destroyed colony would then be rebuilt in a matter of year, done by most of the surviving engineers of the colony.
