Planetary Harvester ships can be seen in every system in the Immortal Empire. They have no standard design and can range from less than a mile across all the way up to the size of a small planet. Although, those of planetary size generally don’t move and act as artificially created forge worlds. There are currently none of that size in Ancerious. Each Planetary Harvester is built around an atomic furnace and nanolaything facility. The rest of the ship is taken up by engines, plasma generators, and storage cells. This leaves little room for the actual crew.
These ships roam the empire’s systems harvesting any and all forms of matter, breaking it down into subatomic particles for storage and later use. They can either deliver these subatomic particles, commonly called ‘slag,’ to forge worlds, where it will be used to fuel the massive foundries. Or the ship can use it to create whatever the crew wants. Provided, of course, that it fits inside the nanolaything facility.
Planetary Harvesters can, assuming the demand for slag isn’t too high, use its nanolaything facilities to improve itself. It is this self improvement that leads to these ships becoming the size of planets. This generally isn’t done too often, because the crew of these ships make their living be selling the slag they harvest. While a bigger ship can more easily harvest larger objects and store more slag, if it becomes too big it also becomes too expensive to operate. If they become even larger it is better to just use it as a forge world.
Planetary Harvesters generally have only light defensive and offensive capabilities. This is mostly due to the fact that weapons and shielding take up space and power that would better be served for storage and matter processing. There are exceptions, mostly from captains who are overly paranoid or have been pirated before.
Notable Planetary Harvester: ‘Dragon’s Keep’
The ‘Dragon’s Keep’ is by far the single largest artificial construct the Immortal Empire has ever made, easily eclipsing most solar systems in size. When the ships known as Planetary Harvesters were first made, Klester bought four and tasked one of the captains to make his ship as large as possible. The other three where told to help him in his assigned task. Currently, the ‘Dragon’s Keep’ acts as the capital of Region 1 and Klester’s personal fortress.
In case it isn't obvious, blatantly ripped off from Star Wars
Also, this is a civilian vessel for harvesting resources, not a super weapon.
THIS would be a super weapon.
