What is the relationship between the Querian Empire* and Solar Empire?
The Querian Empire was once a part of the Solar Empire, when a human trillionare (you would expect to see this far in the future anyways) and philanthropist named Arnold Forrester payed the SE Government for a sector of space that had been donned as the slums of the SE for decades. Forrester invested money in these slums and turned them into his own empire, which remains to this day a small human empire led by Forrester's son, Julius Forrester. It continues to expand, and can hold its own against the Iconians.
TL;DR, The Querian Empire and Solar Empire are Neutral/Allies, though they prefer to stay out of each other's politics.

Name: Sir William Gildshire
Age: 58
Backstory:A former member of the Solar Empire research team in Theoretical Astrophysics. Worked in the research of gravitational forces and the manipulation of them by a substance called Gravitanium, which is a gel-like material expelled from wormholes. Gildshire was knighted for his work with Gravitanium, due to his experiment of levitating a heavy freighter and moving it throughout the air with nothing but an energy source and a Gravitanium-driven engine, which he called the Multiple-Purpose Gravitation Propulsion Reactor (MPGP Reactor).
What is Gravitanium?Since black holes compress matter together and destroy subatomic particles in the process, the corresponding wormhole emits unusual energies and particles. These particles, which were discovered by Gildshire 23 years ago, were dubbed as Xanions, which emit a large amount of Gravitons when electrons pass through them. Xanions form the center of the Gravitanium "atom," which consists of one Xanion (consists of anywhere from 248-924 Quarks) Most Xanions are extremely unstable, and as a result, only 8 isotopes of Gravitanium have lifetimes over 0.00003 seconds. 5 of these isotopes can exist for as many as 4 days, and the most stable 3 have elimination periods (the equivalent of a half-life) of at least 4 billion years. The most stable three (Gn-158, Gn-159 and Gn-162) are used in Gravitanium rods.
Gravitanium-158Application of Electrons: Produces normal gravity.
Applications of X-Rays: Produces Microwaves.
Applications of Gamma Rays: Produces Neutrinos.
A general fuel in MPGP Reactors. Requires control rods.
Gravitanium-159Application of Electrons: Produces X-Rays.
Applications of X-Rays: Produces Electrons.
Applications of Microwaves: Produces outwards gravity.
A general fuel in MPGP Reactors. Requires control rods.
Gravitanium-162Application of Electrons: Produces strong normal gravity and electrons.
Application of Alpha Particles: Produces Neutrons.
Application of Radio Waves: Produces Antiparticles.
Upon compression: Produces moderately strong outwards gravity.
A general fuel in MPGP Reactors. Requires control rods. Must be housed in double-thickness White Carbon cylinders.
Gravitanium is harmful to all except inert or nearly inert matter. This means that it will not cause deterioration in the noble gasses, gold and pure carbon. Extremely hazardous to organic matter.Where is he now?Currently a prisoner of the Iconians, forced to do research on Gravitanium and its properties, and to develop Gravitanium-based engines and weapons in a nearby prison that also serves as a private research facility. He and his colleagues are the only prisoners.
Personality:He is a quiet person, never shot a gun (unless it was to pick up objects with his gravity gun).
Also, what is this crap?
