Humanity continued progress. Step by step, they strode forward into the future. While those steps were admirable, they were all outclassed by the massive leap forward brought about by the discovery of the Lynes, matter accelerator devices that would allow the ships of humanity to traverse the galaxy nearly instantaneous. That was when humanity was not alone in the galaxy, not by far. The universe became that much brighter on that day.
After the Solitude Protocol, and the Fiend Century, the Universe was bright again. Our story begins in the Stone Nexus. This is the home of Zatch, an ordinary human at first glance.
This is understandable because it is of the utmost importance for assassins to seem normal at first glance. In reality, Zatch is far from normal. He is Splintered.
