Here's a tentative WIP from me.

[hider=The Segremony of Spain]Location: Spain 
 
General Introduction 
 
The Segremony of Spain stretches from the Balearic Sea in the east to the North Atlantic Ocean in the west, bordered by the Bay of Biscay in the north and separated from its Moroccan and Algerian neighbors by the Mediterranean to the south. With a French stranglehold cutting them off from expansion into Europe more and more of Portugal cedes to Spanish influence, the small nation unable to resist the tide of illegal immigrants pressured out from overpopulation. Impoverished the peasantry ekes out what subsistence can be found amid the densest and most ethnically diverse population in the world. 
 
History 
 
By the time the black death began to ravish Europe Spain was already leading the world in medicine and in their hubris boasted of a treatment they'd yet perfected. Word of this 'miracle cure' spread nearly as fast as the disease itself, leading to a great exodus of the sick and dying. As a result the plague funneled itself towards Spain and smashed the country like an irresistible wave; galley after galley, cart after cart of the infirmed would arrive, in time their wasn't a healthy soul in all the Kingdom. 
 
To their credit Spain truly was and remains the mecca of medical knowledge, even if it was taxed to the breaking point thanks to a seemingly infinite supply of infectees. Without a cure and with most of the arrivals too far gone to save had they had one all that science and magic could achieve was a sort of stasis--a near death that did nothing to ease one's suffering or render them any less contagious. Now a once proud Spain--previously on the cusp of becoming an empire--leads the world in crime, drug abuse and suicides. Newly dubbed a 'Segremony' their national policy is one of extreme isolationism and limited trade as the disgraced royal line seeks to contain any future outbreaks. 
 
Government & Society 
 
The Segremony exists in a state of collapse and while the royal family still technically governs the nation most if not all of the real power rests with the Fraternidad de Médicos, a sort of medical mafia if you will. Comprised of the most learned doctors and mages the country has to offer they exert their influence indirectly through the subtle understanding that without their stewardship the black death would quickly rise to swallow Spain anew. A representative from the Fraternidad sits on any council of import--up to and including the King's court--serving as spies rather than advisors. 
 
[hider=Los Manchamarcado+] Roughly read as 'the blotch marked', such is the Segremony's largest demographic. A hodge-podge of any and all races that were susceptible to the black death and desperate for a cure/forcibly exiled to Spain. Each would be but a typical example of their ilk were it not for the patches of blackened skin, hideous buboes and slick gloss of fever sweat. Betided by woe they are the very backbone of the drug-economy and listless workforce. [/hider]
 
[hider=Imitadores+] Literally 'imposters or imitators', a racial slur bestowed with contempt upon any nonliving that come to reside within Spain. While not expressly a crime to be undead or some manner of construct/mystical creature many harbor fear and hatred for them, feeling they've somehow profited from the black death. In actuality however many of these poor souls are merely victims of sickness themselves. Imitadores live so far below the poverty line they may as well be slaves or livestock. [/hider]
 
 
Economy & Industry 
(What are your primary exports and imports? How much you trade? How are your craftsmen organized?  How developed is your technology? What kind of unique creations you have? etc...) 
 
Military Overview 
(Yeah, of course you also need to tell us some about your military. Try to avoid number games and unhealthy arms races. We play this game for fun and that needs balance and sensible approach. One of the main guidelines is that your nation's military shouldn't be much better than a historical 15-16th century army. Don't worry, I don't ask you historical accuracy. So-called "super units" can be okay if they are rather rare and may have other limitations. The point is to let you do cool things and explore your creativity but at the same time don't do it at the expense of others.)[/hider]
