The Crystallin Matriarchy
The Matriarchy began as a common kingdom in the world and occupied the northeastern parts of the Peninsula. The rigorous Matriarchy where only women are considered free, began during the days of Queen Arminia Zenobia who defeated the treason of General Breder and swore to never trust a man again after his rebellion. After that, warrior women started coming to the Crystallin lands from all over the world and today, the Crystallin fill their ranks, not only with women born within their borders, but indeed from all over the world. This makes the Crystallin army deadly dangerous, since its ranks are often filled with criminals and such elements, as no questions are asked when you join the Crystallin ranks, and all women are welcome, and a grudge against the rest of the Patriarch World is considered an asset.
Men are considered unfree and are treated like slaves. These conditions have been considered barbaric by the rest of the free world, and delayed the Crystallin inclusion into the Empire and severed relations to other kingdoms. The Crystallin nation is led by a Matriarch with a court of intellectuals advising her, and the individual provinces have their governors, but the Empire is really only held together by the army and the steady addition of new warrior ladies from all over the world. The Matriarch lives totally secluded from the world with her hundreds of female servants. No men are ever allowed to approach her at her "Secret Palace" and all foreign diplomats wishing to speak to her or her government have to be female. She is guarded by the Elite Matriarch's Guard who wear the traditional black armour which made the Crystallin Matriarchy famous in the old wars.
The state philosophy which is overall accepted is that which Arminia Zenobia wrote down in her "The Nature of the Matriarchy". The Crystallin consider themselves the only defenders of Women's Rights in a Patriarch World and this higher ideal gives the state and army its meaning and fundamental way of thinking. It has also led to really rigorous laws in the relations between men and women within society. Men are held as slaves and romantic relationships are - while not forbidden in law - indeed forbidden by social, unwritten rules. The higher ranking officers, noblewomen and royals often keep large harems of men, meaning that the annual slave market in Djenina is well-visited by these nobles who wish to get themselves new additions of fine male specimens to their harems; the annual Djenina Market has become the joke of the world. Principality drill sergeants threaten their recruits with "Do your best or I'll send you to the frontline at the Djenina Market!"
Due to its small aristocracy, clear rules and social systems and common enemy in males everywhere, the Crystallin state functions best in war. That is why the Crystallin leadership is known to always be on the lookout for new wars and conflicts to take part in and they indiscriminately go to regular wars against their neighbours. Their politics are known to be some of the most aggressive in the world as they seek to "Liberate Women Everywhere". They are also known to form and uphold really true and loyal alliances when threatened by a greater evil, like during the days of the Great Wars when they allied with the rest of the Eastern Nations to defeat the Demon King.
