Vysokiy was your typical nation after the collapse of the Alammar Empire, founded in the northwest by a popular governor of the region, Chudakova. He proclaimed his right to rule was ordained by the gods (even though he wasn't an Emissary himself,) and set out to build Vyosokiy. Chudakova quickly grew a reputation as being quite eccentric, choosing to build his castle at the footsteps of The Urysas. He had originally wanted to build the castle at the top of the mountains, but his advisors managed to talk him out of it. Despite these eccentricities, Chudakova proved a talented enough leader, growing Vyosokiy into a major power in the north, establishing themselves as an ally of the Kingdom of Falglor, which was another powerful nation after The Splintering. Most of Vysokiy's economy was based on exporting minerals and different ores they extracted from the mountains because of their proximity to the things. A fatal flaw was the Vysokiy was heavily reliant on foreign imports for crops, food, salt, and other different materials. Chudakova was aware of this, and decided to try and remedy this through conquest.
To the north of Vyosokiy was a smattering of shattered petty Ravennan states that desperately struggled for power, warring with each other constantly. The soil they were on was great for growing crops, and it would provide much more land for Vysokiy to expand and establish itself as more powerful nation. Chudakova pressed claims on the northern territory, and hoped to portray himself as a liberator for the Ravennan people as he invaded. The invasion went off without much of a hitch, the better prepared and equipped Vysokiyian army easily defeated the barely trained and equipped conscripted peasantry. While there certainly were some attempts to resist the Vysokiyian occupation, Ravenna was mostly under the control of Vysokiy. Chudakova instantly set about developing the new province, granting it some degree of self-rule, and developing a new branch of government for the new territory, much larger territory. There was many problems with discrimination against Ravennans, to such a point where it was more common to hate Ravennans than it was to not hate them.
Vysokiy under Chudakova mostly prospered, even though the King was a bit crazy. Eventually, Chudakova died of tuberculosis, and was replaced by his son, Shikea Bezumiye. Shikea was much less savvy then Chudakova about running a nation, and much more unstable too, in the emotional sense, not a mental sense. People were hopeful about Vysokiy's future, but that hope was soon to come crashing down.
Before the tide of things that happened that were out of Shikea's control, he made one bad decision, and that was purging most of the King's Cabinet and replacing them with his own people. People like the Treasurer of State, or the Marshal of the Armies were replaced with yes-men who followed Shikea's every command. The only one who was not replaced was the old Chief Advisor. This move didn't really cause that much discontent because the common person mostly didn't care about things like the cabinet and weren't really involved in politics that much. Then, things started to go downhill. The eastern neighbor of Vysokiy, the Grand Duchy of Tanat, started probing the borders of the kingdom, sometimes even sending troops to raid border villages.
A blight in the recently acquired province of Ravenna started to kill many of the crops that were vital to Vysokiy and Ravennan survival, which the Committee for the Efficient Management of Ravenna couldn't deal with because their branch of the government got gutted by Shikea. Officials in the government scrambled to try and stop the spread of the blight or at lease minimize the damage, but it had spread like wildfire, and now Vysokiy was out of food. Shikea decided to put Vysokiy first before Ravenna, which was completely rational and acceptable, except for the fact that this entailed that all the rationed food stores would be redirected to Vysokiy, and that Ravenna would be basically left with nothing and were free to starve on their own. This caused the Great Ravennan Famine, which killed thousands. Because of this, Vysokiy had to ignore the raids from Tanat, and start to import much more food to feed its people.
To pay for all this, Vysokiy took a gigantic amount of loans and also forced its miners to work harder in order to compensate. Overseers worked miners to death, literally, in terrible conditions without sleep or food, with little to no pay. Tired of this treatment, the miners revolted, and stopped working. This caused Vysokiy's most valuable export, the thing that was keeping their economy together, to simply stop, causing a collapse of the market. The legitimacy of Shikea on the throne was questioned, and people started spreading rumors about how Shikea was cursed, and would doom the nation. Shikea desperately tried to stop these rumors, which only poured fuel on the flames.
All these different factors started taking a toll on Shikea, who started to lose it, randomly violently attacking people who made him even a bit mad, and executing people left and right, which did little to aid the dire situation. Things got even worse however, with the outbreak of the Age of Frost, in which Vysokiy was the first on the target list for the Armies of Dread, who quickly defeated the ill-prepared and underfed Vysokiyian troops, who were led by an incompetent marshal and generals. All of the armies fled into the Vysokiyian homeland, leaving the Ravennas to die by themselves.
When the Armies of Dread were driven back and defeated, Ravenna revolted, and Vysokiy could do little to stop them. By this point, Shikea was an insane mess, who lived in hiding along with the rest of the government and a bit of the army. He later died of an aneurysm, which was the last straw. Without a leader, government, economy, land, or an army, Vysokiy was a failed state, and it collapsed.
