There are four varieties of nihil, each created from a specific race and attuned to one of the four elements of the ancient magicks. They are fought as bosses on freneskae during fate of the gods. Web the nihil saw themselves as riders of a storm that swept through the galaxy, allowing them to take whatever they wanted. Nihil tibi a me postulanti recusabo. That is, in law, irrelevant and/or inconsequential.
