Prologue:
Earth: year 14023
It has been many generations since humans were forced to leave their homeworld, Earth. Due to the global warming started by the global coal revolution, that started getting recognition around the year 12000 of the human calendar.
The sea levels rose sharply and greatly reduced the available amount of land and fertile soil, entire countries disappeared quickly and were swallowed beneath the waves, the arctic tundra thawed, releasing enormous amounts of captured CO₂ back into the already strained planetary atmosphere.
Modern humans now live either on the small amount of land left, or in floating and underwater megacities, as almost all land above the sea level was precious and destined to be used primarily for huge farming complexes.
The colonization of other planets like Mars was accelerated, quickly expanding the colonies both there and on the Moon Station. Meanwhile on Earth, underwater farms thrived, and after centuries of development, the planet stabilized with humanity largely adapted to life in its cities.

Earth: Year 12905
Advanced life-extending genetic technology was finished being researched, and a UBI(Universal Basic Income) was implemented. Due to this people usually only started working at around 100 years old and were considered legal adults at 50 years old. During this time advanced genetic modification was very popular and everyone could be whatever they wanted.
Earth: Year 13026
Sophisticated cryosleep technology was invented, now humans could be kept frozen for long periods of time without being harmed by the extensive cold they were subjected to.
Earth: Year 13853
High-speed antimatter space engines were invented. They used a mix of dark energy source warping and antimatter propulsion to quickly transport a vessel from one point to another.
Earth: Year 14023
The first private colonist company finishes the large first phase of their huge colonization project of the planet Gliese -581c. First, they will send an engineer along with robots to set up the beginnings of a successful colony, and if things went well the company had its eyes put in the super-earth Kepler- 452b next.
