From the edge of the misterious system, an even more misterious event manifests itself. In an about 300 meter bubble, space starts to fluctuate. At the beggining, small fluctuations happen, quantum-escale fluctuations seems to get stronger and stronger, and eventually, the event almost becomes macroscopic.
And from that particular bubble of distorted space-time surges a ship, almost as if turning a corner on reality, it stands there, still. It has no markings to be seen, its hull fully a dark-grey, broken by small blue-ish metal pieces, and slightly illuminated by the glow of its engines whose red-turned-white hue emanates a dim light.
It stands there, motionless, observing what is in the system, nigh-imperceptible due to its natural camouflage.
