Noverian-Archive Experimental Divorare class - The Divorare class is literally a black hole ship, after the Archive discovered the effects of linking Noverians to a Black Hole they got more volunteers and started to create the Divorare class, the Noverians were immune to the Black Hole's effects, this included the gravity well and the TD field. And like with Miggaitt they were capable of controlling it, by creating habitable space inside the black hole and lining it with Gray Matter the two empires working in tandem have created the Divorare class, it's powered by an internal propulsion system that uses the black hole's ambient radiation. It has no weapons but it doesn't need any, it uses his very nature as a weapon. But the Noverians can also launch small pieces of the black hole as a basic ballistic weapon, even a SUV sized chunk can do a large amount of damage, due to the mass and speed. It's staffed by linked Noverians and Archive scientists, it's around the size of a Texas.
Interceptor device - This device can intercept most known types of intergalactic travel, ranging from Hyperspace, Jump Driving, and Drift Space. But it has a limited range, if a ship tries to pass through the affected area with a type of travel that can be intercepted it will exit the travel, or stop immediately.
