Ok, this is a quick summary of the kind of nation I'd like to play. Tell me if you think I could improve it somehow:
The Republic of Koninkryk is a small (by galactic standards) empire, believed to be relatively new to the stars. As new as they are, they have expanded quickly, with world after world pledging fealty to them. That is not to say, however, that they are aggresive. Far from it, actually, as many of their worlds were either uninhabited or won over by their advanced technology and silver tounges, rather than force of arms. They have gained many new races and species, all of which are treated with as much equality as possible.
Koninkryk is predominantly matriarchal, due to its roots on Huisward. Here, women are taller, faster and stronger than men, who are considered to be weak but cunning. Thus, it is women who are more likely to arrive in positions of power than men. Indeed, there are but two males in the Republic's parliment - Weiss Feder from Huisward and Drakvarde from nearby planet Skygge. However, this is not considered a downside or negative in any way by most of the Republic's residents, male or female. High-ranking positions are seen as those of responsibility, not power, and it is well known that without the general workforce, the entire Rebublic would collapse.
Speaking of the general workforce, there are many creative, unique and exotic exports from Koninkryk. Many of these are meagre trifles, pretty but otherwise uninportant, but there are a couple of big sellers, namely gemstones and weaponry.
Gemstones in Koninkryk are not small, shiny gems like those of Earth. Each stone is crafted and carved by the elements themselves, not by stone-cutters. They are imbued with power that allows them to be used like conventional power sources. These are doubtlessly cleaner and more powerful than most batteries and fuels, creating zero toxins or waste, but cannot be recharged by normal means. The secret of recharging the stones is kept within the Republic under pain of death, so the only alternatives to returning the gem is to resort to normal power sources or buy more gems. However, chargeless gems still have some use - they retain their strength and sparkle. This means they can be used to replace normal gems in a pinch.
Weaponry is vastly different to the weapons of most other empires. In Koninkryk, soldiers are trained to incapacitate and disarm, not slay and conquer. To meet this strange order, weapons are designed to knock out, paralyze and otherwise render enemies useless without killing them. Even melee weapons are treated to bust through armour without hurting the wearer, and anti-vehicle devices work by frying the electrics and jamming the motors to avoid unnecessary casualties. Even space-faring craft have unique cannons designed to stop other spacecraft from firing back. These weapons are appropriately named "Disruptor" weapons
Disruptors have an adverse effect on robots, cyborgs and other robotically and mechanically enganced beings. Direct hits can result in the creature being disabled, and even glancing hits will set off the creature's closest thing to pain receptors. Cyborgs have reported being incapable of using their mechanical limbs and enhancments for months, even years after the initial shot. Even expert engineers seem unable to get the devices running, short of replacing all the wires and batteries. It should be noted that the aforementioned gems will lose all charge if the suffer a blow from a disruptor, as will some types of battery. In these cases, simply recharging said battery will return it to full function. If this doesn't work, there is no choice but to wait for the device to start working again or replace it. The more power a machine requires to function, the longer the wait. Whereas simple weapons may take a few minutes to unjam, complex vehicles and tanks may take several hours to clear up, and spacecraft could take weeks.
