Parasitoid hunter

"In time the parasitoids became a nigh accepted fact in the less monitored regions. Mind, they were not prevalent, but still prevalent enough that one had to be mindful of the fact that at any moment a cloaked vessel could ram into your ship and the parasitoids would pour in. In time also the parasitoids began to change shapes, more and more different forms of them were sighted, some serving very specific niches in either their own hives upkeep or in assaults onto uninfested ships.

After the infestation and capture of one of the flagships of the united space faring peoples, the parasitoids now held a vessel which could not be destroyed with standard ship weapons. Despite this, they seemed to steer clear of the more populated areas and stayed in the silent sectors. This massive ship would float idly there, but the interior of it was more alive than ever with alien life."
