The Relic of Rukhial

The Relic of Rukhial was a ancient Precursor artifact left under the crust of Rukhial. While originally buried deep in the crust of Rukhial, after discovery it was thought to be a massive Precursor city, but when the Jigaria gained control of the planet they realized that it was infact a massive starship that had the ability to destroy and entire planet.

History
Believed to be an ancient Precursor Colony Ship, it was probably landed on Rukhial and was colonized becoming the center of that world. After the Precursor oddly disappeared it slowly began to disappear due to sediment covering it. When it was disovered by the early colonists of the Arkhangelsk Empire the Arkhangelsk thought it was a massive city, with its many tiers and towers resembling a city. During the Arkhangelsk-Jigaria War, the Jigaria overtook Rukhial and discovered the massive city, which they soon found out was more than just that. Extensive studying discovered it was a supermassive colony ship, that had the power to warp to a location in an instance and destroy entire planets.

First sighted orbiting Arkot by a small Arkhangelsk Royal Military Command patrol, it destroyed and obliterated the planet in a single shot, terrifying the Commander and causing a full retreat to Arkhangelsk(planet). After some time the Jigaria warped directly into Arkhangelsk(planet) space and proceded to try and destroy it, but due to the selflessness and heroism of the Ascended Justice Fleet, the planet was saved and the relic was destroyed in the ensuing blast.

Desgin
The Relic was designed to ferry colonists to far off worlds, and when landed it would become a city. Modifications were made to it to and towers and buildings were build on it, but they were still attached to the main ship. The ship had the defense capabilities of some of the Royal Arkhangelsk Navy most powerful ships but only being a colony ship this is very admirable. While being as large as a small capital ship it still had the ability to do pinpoint interspace jumps and also had the power to move itself at suprising speed.

Other Relics
Speculation brings out that their must be similar colony ships on other ancient Precursor worlds. It is thought that one resides under the superstructure and crust of Arkhangelsk(planet), but this cannot be validated in anyway. Other relics were found on the relic before its destruction such as a datacube known as Krktos, it has yet to been deciphered to this day.
