Fiction:Cognatus Remnant/Navy

Genesis
A truly monumental structure. At over 40 AU in diameter, it is one of the largest structures in the universe. It was built by the Cognatus, some of its capabilites include the creation of stars, trans-universal travel and galactic annihilation.

It has given the Cognatus a gigantic boast in technological abilities, with it, the Cognatus has adapted its energy into their own ships, letting them colonize hyperspace, making them more or less invincible. Such a huge structure it is that it has the size of the distance from the sun to the Scattered disk, beyond the Kuiper Belt. It is also one of the most dangerous weapons ever built with the power to quickly and quietly kill everything in a galaxy by killing neurons in the nervous system, another more disastrous way of doing this is actually artificially increasing the gravitational pull of the super massive black hole in the galaxy causing the stars to get caught in the drift and into the black hole.

It is truly an achievement.

CCS Class Battlecruiser
The CCS Class Battlecruiser is the most common vessel present in the Cognatus Navy. At two kilometers long, the CCS is a large ship and yet small enough to be underestimated. It is highly effective at what it does best, glassing planets, ship to ship combat and destroying simply all it sees.

It is an old ship and new, more disastrous ships are being built after the Intergalactic War, however this ship is best known for glassing planets, it was instrumental in destroying many URC, Rambo and DCP colonies, simply due to its highly advanced shields.
