Congratulations, you have been selected to undergo breeding restrictions.  By choosing a gender identity which is symmetrical you have a 50% chance of being sterile.  This sterility can only be overcome with increased breeding groups and the permission of the reproductive instituion.

What are your gut reactions to being told you do not have the right to reproduce?

Did you know that it is for the greater good?  The world can only sustain a certain number of people comfortably without straining its resources and causing imbalance.  So then, why you?  Well, nothing personal.  The genetics of assymetical gender identity individuals has been observed to be higher, so a proportion of those of us without such a condition are randomly ineligible to breed.  Like the rest of our social system, there is room for flexibility.  Upon the submission of a breeding proposal, your eligibility will be re-evaluated.  Note that you can only make one such request in your lifetime.

The breeding conditions were laid out as a result of the Evolution War.  The main point was whether we as a species wanted to be conscious of our reproduction and resource use as it spiralled out of control.  The Red nation held the opinion that all should be able to breed freely and that harsh selection could optimize the species within a shorter time.  The White nation felt that breeding should be restricted and planned, along the well-known principles of plant and animal breeding which has been established for many thousands of years. 

Outcast Nations and some of the early Mecenasnuro tribes opposed them both.  They felt that controlling the breeding was wrong and that all should have the freedom to make whatever use of the environment as they pleased.  As the war waged on, the outcast nations and the mecenasnuro became marginalized, and became the target of Animal nations as a result of perceived injustice.  The Dual supported the establishment of breeding oberservations, but wished to remain impartial of the war.  They did supported the animal nations, which eventually lead to the exile of the Outcasts.  Some of the Mecenasnuro fled to the Outcast continent, others fled half way to a sizeable island which they declared a sovereign nation independant of the world government (but still distinct from the outcast nations politically) and some tribes stayed in the mountains of the main continents.  Those continental Mecenasnuro living adjacent to Red and White nations agreed to impose limits upon their breeding.  However, the way the alienation and family group restructuring had already gone through this war meant that they did not desire to breed profusely, nor expand.

In present day, the breeding practices of Red and White have achieved general consensus with a bit of regional variation.  The Mecenasnuro follow suit, but the Outcasts still insist they should be able to breed as much as they damn well please.  As a consequence, their continent is highly over-populated and fiercely competitive.  There is a greater division of castes and unequal distribution of wealth.  Every so often the Outcasts will send ships (or refugees flee) to the main continents or the Mecenasnuro sea land.  These ships can apply for immigration if there is enough space and resources available (10% chance), otherwise they are given two options:

• Go back to the seas and find your own home
• Volunteer for the Demon Siege and be given provisions and a permanent home at the Demon Gates
  • Individuals and groups who have committed 20 years to the Demon Siege are given full world citizen status
  • This is not necessarily a death sentence, as they can work within the supporting communities rather than the front line
  • The term can be shortened if they aid in a major military campaign
  • Temporary visas to travel the main continent are available
    • Those who do not return on time are considered fugitives, and forfeit all rights under the law.
    • The vigilantes are swift in tracking these individuals down and getting them exiled permanently

Not every ship will agree to these rules, and sometimes peaceful refugees are whipped into an unfortunate passion which turns them into pirates.  However, coastal cities are some of the best fortified, and port cities are generally understood to be dangerous and shifty places.  The laws are sometimes loosely enforced by sheer necessity of the chaos within them.  The chaos is not allowed to leak out though, and there is a secret agency of bucaneers who pride themselves in bringing justice to the waters and peaceful fishing villages.
