Once upon a time, at about 12000 years ago there was a legendary and mystic
Terrestrial league. Overpopulation lead people to explore the  outer  space 
and so it was an era of peoples spreading. The humankind had populated 
several thousands of worlds inside the galaxy and even some worlds outside
it. 
Then due to multiplicity of colonial wars and wars for  independence  the 
Terrestrial league was broken and worlds began independent life, deep sunk
into their very own problems. Thus began the forsaken ages.  Most  of  the 
advanced technologies were lost. Interstellar flights and communications 
are among them. The humankind spread over the galaxy suffered from low
culture and feodalism.
About three with a half thousands years ago the new era had started with 
risng of two progressive worlds. Those were Verzandi planet and Pexion planet.
Both were advanced enough  to  rediscover  the  faster-than-light  travel 
technologies almost simultaniously. The situation was sharpened by the fact 
that bos solar systems were separated by a distance less than one hundreed 
of light years. Certainly the war between worlds has started. 
However governments of both worlds were wise enough for not to let the war 
to lead to heavy destructive consequences. The peacefull pact was signed, 
where union of Verzandi and Pexion solar systems was proclaimed. 
This was the birth of new state - The Confederation of the United Suns.
After that many and many worlds were discovered and became part of the
Confederation. 
The more worlds were gathered around Verzandi with Pexion, the more powerfull
became the Confederation of the United Suns. Many of the lost technologies 
were rediscovered and the new ones were developed. Particularly in addition 
to 'tachion bubble' method of faster-than-light travel, that is supposed to
be known in the lost Terrestrial league, there were also discovered other 
new methods of interstellar flight. Among them are the two-dimensional collapse
jump and the direct quantum mass interchange (or simply "null-transfer"). 
Authomation and droid technique lead to mass production of pseudo-sapient
systems, that exhibit a clearly intellectual behaviour at the highest human
standarts.
The development of the nanomachines and biomachines had opened the way for
human body modification. Thus implants of million types became available on 
market. Some of them were for life extending or desease treatment, others 
offered all kinds of body enhancement.
Moreover the achievements in medicine and genetic engineering lead to the fact
that trillions of clones and genetically modified species were poured into the
population of the CUS. It became obvious that if nothing was done the human 
genome would be lost forever. So the laws establishing bonuses for clean 
genome carrying and penalties for genetic and technique bogy modifications 
vere established. However those who had such a body modifications did not 
obey restriction in rights and the well known Civil War has started. There
were four large groups that fought for their rights:
 - Humans - rather genetically clean species, 
 - Androids - the technically and cybernetically enhanced humans,
 - Mutants - rather heavily genetically modified species
and 
 - Droids - artificial species who had not their origin in nature.
One should note that a species originating from natural beings affected by 
genetic modifications are called 'mutants' but even biological creatures 
fully consisting of flesh and bones are called 'droids' if they have no 
natural origin and are created 'from scratch' in biogenetic laboratories.
At the beginning of the Civil War all groups fought against each other for
their very own interests. The turn moment came when humans made a Union
with Androids against two other groups.
After 300 years of war Humans and Androids were victorious and the new 
order of races was established.
Humans are the most rightfull race and social elite.
Androids have the most rights with a little rstrictions.
Mutants have even more restriction in rights and the main handicap is that 
their reproduction is stricly controlled.
Droids are the lowest race and it is prohibited for them to occupy the
supervising posts. They are usually servants and work on auxiliary jobs.
However it is incorrect to think about them as 'slaves'. Droids are citizens
of the Confederation of the United Suns, their interests are always kept 
in mind by the state, and their rights and life are under the state protection.

The last 700 years the CUS lives the comaratively pecefull life. However the flames
of local conflicts do not fade away for centuries. So one of the basics of life
for the Confederation is to have powerfull and advanced military forces. There are 
six starfleets: North Fleet, West Fleet, South Fleet, East Fleet, Axis Fleet 
and Domestic Fleet, named mostly by areas of the Galaxy beung under their authority.
Each fleet has a powerfull group of starships of different classes and also 
powerfull landing armies.
The core of the strike forces are military androids and battle mutants. However
one can not say that humans had left military actions for other races. Many of well
known war heroes are humans.
When speaking about military forces of the Confederation of the Unites Suns the 
special word must be said about the kidder forces.
As it was shown in the past battle conflicts droids exhibit inadequate flexibility
leading to high losses and low probability of victory against troops formed by
natural and semi-natural beings. So the necessity of the remote controlled 
and mechanically empowered units is critical to the battle success. However the
adult beings have shown themselves to be able to succesfully operate olnly one
or two battle units. It was discovered that children in the age of below 18 have
a good abilities to split their consciousness for the complete and independent
control of 4 to 10 battle units. With aging this ability beccomes weaker and 
usually completely lost after 20 or elder. This precious ability was not left 
without attention and came onto the social service with forming of  special kind 
of troops was formed. It became known as 'kidder' forces.
Nowadays almost no advanced space or even land battle could be imagined without
a support of kidders. However as being children they are not allowed to directly
pilot battle vehicles or take part as infantry units during real battle actions.
