Terrashaping was an experimental technology originally developed by the Lo'Xal Federation in the year 7901 CE, but finally independently developed by human scientists in 10,108 CE. This technology involves bombarding worlds with asteroids and heavy duty lasers to create and carve a desired shape for continents and oceans on many different planets. Other forms of terrashaping include moving large lots of land, one at a time for centuries until the planet would have a desirable shape in their continents.
The idea for terrashaping was not a new one, but the many scientific communities of the Confederacy had largely ignored it due to what they thought was its frivolous nature. However, scientists on Lo'Kira decided to use this to create wonderful islands on planets, and later used it to reshape their homeworld.
Scientists within the Confederacy independently began developing this technology thousands of years later and on August 25, 10,111 CE, work began on the recreation of Earth around the world known as Gaia located within Thulcandran Space. Its moons were torn apart, and the larger one was created to imitate the pre-terraformed Moon. The process was painstaking and precise and took many centuries, but eventually Gaia's terrashaping was complete. This was done by the corporation now known as Tundra, who now specializes in the sales of electronics and megastructure equipment.
This technology has been used since to create planets with customized islands and coastlines, sometimes with various messages being carved or placed on the surface. as well as recreating worlds that had been destroyed. The Terrashaping technology is useful for "sculpting" worlds, but must be done on lifeless worlds.
In order to carve a world, there is a rigorous selection process that must take place beforehand. The main objective is to find a sterile world that fits the specs of the world that is being created within an acceptable margin.
Next, large and powerful lasers are brought into orbit. Depending on the size of the planet, the lasers will either carve out some of the planet's mass or asteroids will be shot into the planet to add mass. When the desired mass is achieved, then the lasers are programmed and begin to sculpt the world below. With the help of powerful tractor beams, any excess mass is either moved off the planet or moved to a place where it is needed. Once the rough cuts are done, the lasers are fine tuned and focus on any finer details.
Once the process of carving the land is complete, then comes the normal terraforming process. The world's orbit is fine tuned, an atmosphere is added, as is water and plant and animal life. Once that is done, the process is complete.
