The Vengance is a one of a kind vessel. All Razureth ships are like this. A rRazureth bonds with his ship and his ship bonds both physically when on board and telepathically when not. Razureth ships are sentient in their own right. They are among the few ships capable of reproduction.
The Vengeance is the last Razureth ship in existance but is pregnant with 150 "children". Like lifeforms the ships grow larger as they get older. they also gain more power as they age. The Vengeance feeds off of heavy metallic asteriods in space as well as being able to paristicly feed off of other ships as well for susteance. They can even devour black holes for energy. Like lifeforms the vegance follows the same basics except that they don't decay as they get older and instead grow more and more powerful.
The ships of the Razureth are known to go insane if their bondsman dies. When they do they will relentlessly seek out who killed them. If they succed in the killing they will commit suicide.
