Gaining Military Access

The holographic projection clearly depicted the terra formation of several celestial bodies within the borders of the Germanic Star-Empire, so much so that S'varin's eyes nearly jumped out of his sockets. Terraforming was an extremely advanced technology that only those Galactic Powers had access to.

It was the difference between searching the void for an unoccupied system that could miraculously support life, and taking a system that was completely barren and turning it into a utopia built from the ground up to be ideal for your species' habitation. 

The fact that the Germanic Star-Empire had such advanced technology, and had been hiding it from the public eye meant that they most likely had various other advanced forms of technology. If that was the case, they might actually be able to detect the Naraku who were still beyond the detection of the Dvrakian sensors, and perhaps even be able to defend against them.
