The Empress sat on her throne, trembling as the enemy approached her Great Hall. Her lower lip quivered, goose bumps formed on her flesh, and the chill of fear gave her the shivers. The Nasucrean Empire had fallen, and there was no saving it. She was the last Empress, the end of a long line of female sovereigns who had dominated the civilized world.
Sadly for her reign, the eunuchs and males had risen up against the matriarchal system of their native land, joining with the Vystercian savages to achieve vengeance for centuries of oppression. When the mercenaries who composed the capital's garrison demanded more pay as the price for their continued service, and the Empress didn't have enough money to meet their demands, they simply joined the invaders and opened the city gates to the barbarian horde. The fiercely loyal Imperial Guard fought to the death, its entirely female ranks refusing to live under a patriarchal conqueror. Those 250 soldiers were not enough to hold back the gigantic Vystercian host.
The war had gone badly from the very outset. It was a complete surprise, when the new Vystercian Confederacy had simply attacked the frontier towns and overwhelmed the neglected fortifications of the overextended Empire. The men of the towns had welcomed the invaders as liberators, instead of resisting them as occupiers.
The fragility of the Empire was proven. Its supposed security had rested on the disunity of the neighboring savages on the borders. That situation was no more. The Confederacy was established by the new High King, Ar-Ges, a chieftain who had once been a hostage at the Nasucrean court. All of the tribes opted to unify themselves under a single command.
The initial invasion was almost totally bloodless, thus reducing the anxiety that most had of life under Vystercian rule. The real fighting didn't begin until the field troops arrived at the front. There was no question of which front that was, in any case, since the Empire was surrounded by the "barbarians" on all sides except the coastline.
Even the battles were pointless and futile. The lower ranks, composed of male conscripts, simply defected to the Vystercians and turned their weapons against the all-female officer corps. The officers were too heavily outnumbered and unprepared to prevent this juggernaut. Most of them surrendered when they realized that it was hopeless.
The interior fell into the enemy's hands in a few weeks, causing the Empress to use her elite mercenaries to flesh out her ranks. The problem was that most of these men were Vystercians themselves, and many of them feared retribution for betraying their countrymen.
Yet another fatal flaw of the Nasucrean state became apparent when it was already too late. Desertions became pandemic in the Imperial Army. Those who didn't switch sides extorted more pay for their loyalty. Military discipline became impossible. No one was motivated to defend a country that existed to provide women with political supremacy these days. The original purpose of the Nasucrean nation was irrelevant and forgotten. Time had made its survival undesirable for the male minority. They had become a fifth column that simply backed the invaders against the old regime.
A desperate Empress had armed the eunuchs who constituted the Imperial civil service and any other male civilians who declared themselves willing to defend the Empire. It was only at this point that she realized just how disgruntled her male subjects were with their station. They mutinied everywhere and aided the invasion force. The crews of the naval warships particularly rebelled against their female captains and first mates. They raided the coastal cities and abducted many of the local ladies. In mere days, the last provinces outside of the capital were occupied by the Vystercians and their sympathizers.
The siege of the capital was short, but the battle for control of it was not. The Imperial Guard fought from house to house, despite the fact that most of the inhabitants simply watched the action instead of participating. After all, it was only women of the ruling class who truly benefited from the services of eunuch concubines. The rest of the women had to make do with only their husbands: fully intact men of equal rank. Only ladies of high rank got to have eunuchs lick their husbands' seed out of their cunts. Noblewomen had these oral services entirely to their themselves. There was a scarcity of men as it was, so eunuchs were a luxury.
Unknown to the Nasucrean rulers, this social custom of eunuch harems and double standards created a population decline and shortage, thus further weakening the state. Reliance on mercenaries became more frequent as a result, to fill in the gaps in the ranks. It also broadened social divisions and created popular resentment, making the bulk of the people of both sexes unhappy with their situation. Only the women of exalted status had any vested interest in preserving the Empire, and their numbers were small. By far the most discontent citizens were actually men of the middle class, who were the ones most likely to be forced into castration and service as a eunuch to either the Empress herself, the Imperial civil service, or noble ladies who had a right to conscript male commoners for their own pleasure.
