Our homes are lost, our history is squandered - for what? The greed of man— furious rebel
The damming of the Imbreagat was the highly controversial construction of
Fusorium Dam high up in what was once the
Imbreagat River. The dam was an initiative by the
Medimian Empire, who sought to provide more consistent water supply to areas of the Empire's southern reaches through the creation of a reservoir.

However, to dam the Imbreagat was to permanently destroy the river's continuing flow -- and the Imbreagat was a major trade river heavily involved in
Arriusi culture as well as providing vital water sources for parts of
Niniéra and the
Vostene Republic, among other lands.
News first spread of the dam's impending construction in 5578 after a well-received announcement by the
Ruby of Trade, the
ruby in charge of all matters of trade and construction. Weather in the preceding years had been harsh, leading to widespread drought and famine through Medimia's lands, and rebellion had brewed with fierce fervour.
Tension with the southern border nations, too, rose higher as accusations of stealing Medimian trade, price-gouging to Medimian customers, and illicit magical practices caused a sharp increase in fights and attempted rebel actions. With weather conditions trending towards ever more severe, Medimia's south began to suffer: if not drought, then floods. If not floods, then blizzards. Something needed to be done.
The dam, according to the Ruby, would serve to not only provide Medimian lands with a far increased water supply, but would also reduce the impact of flooding in rainier times - and would put paid to southern arrogance by removing one of their key trade routes. Certain long-standing routes with a history spanning centuries would need to be replaced with land crossings, or to shift to lower-down tributaries if not other rivers entirely.
Indeed, the dam would reinforce Medimia's position in the minds of many as the entity in control of not only their land, but the ones lying within their reach, and none could actually
stop them.
That did not mean none would try.
The Dam's Construction
If we could just stop it before it could do too much, if we could save our towns, if we could protect the trees...— hopeful rebel
Large-scale construction efforts are no slow endeavour, even with the
Amethystine Regiment's forces being pulled in alongside countless workers and standard military forces. Whilst magic would speed up the process of the dam's construction, it would still take seven years to build the dam itself. Seven years meant plenty of time for furious locals, Arriusi, and other rebel factions to band together in an attempt to stop the construction before it could be completed.
Throughout the construction period, attacks of varying scale came in stutters and bursts.
Virescan citizens coordinated rebellion efforts through their
secret language whilst largely staying out of efforts themselves, per orders of the
Teacup Resistance.
By dividing their approaches, the Resistance's members could be found innocent of any accusations of rebel involvement near the dam, and other rebel groups could be kept out of Resistance plans. This was, too, why the various groups involved had only loose involvements; if the Empire detected too large a force, they risked drawing the Empire's full focus. Such a thing would
never end well.
So the attacks were more often small and subtle. Stones were drowned in water to weaken and crack them, or replaced by lighter, brittle varieties. Construction equipment was stolen, weakened, or broken. Food supplies were stolen away, or mysteriously never arrived.

More drastically, small tremors and explosions were set off in the dead of night to crack parts of the dam, weakening it enough to collapse at certain points and setting back construction by months to years. Yet by far the most significant event of this period was the collapse of the large nearby mines that were providing most of the building material. Rebel forces had received word that the mines were not properly secured further in, and one had recently pierced a well of natural gas that had taken multiple miners' lives.

They crafted pseudo-official letters of notice, and called on the building site's inspectors to see the mines vacated and inspected out of fear of 'rebel tampering'. What the inspectors had not suspected was that whilst they alone were in the mines, a contraption would knock out several support pillars and light the well of gas. The explosion rendered the mines unusable for years; the gas could easily flow through the new openings, nearly suffocating the first folk to check on the damage.
Medimia's response to the mine incident was swift and stern, as it always was. Countless were arrested and subsequently either enslaved or executed, even if their guilt was uncertain. From then on, what the Resistance had feared came true: Medimia's gaze rested on the south, and rebel activities were forced to drastically decrease.
When the nearby valley was flooded to become the reservoir, suspected rebels were - as punishment - locked into houses within as the water arrived to grant them the river they so craved.
With the bulk of the rebellion either scared off or dealt with, the dam was finally completed in 5585.
The Dam's Completion
Completing the dam spared its workers and guards as they were ushered away, and for a time, it seemed like the troubles had ended with the reservoir's establishment, especially as it immediately proved itself useful through times of drought.
The peace was not to last. The dam would come under attack repeatedly over the next few years, with attempts ranging from launched explosives to illegal
arcane mages attempting to destroy it through sheer force.
Finally, after three towns were flooded from a successful detonation, the Medimian army stepped in, backed by the larger-than-life figure of the
Ruby of War herself. Large border walls and surveillance sprung up over the next two years, and the area began to be used as a military training and development site by 5589. Thoroughly stymied by such a display of dominance from Medimian military with no real way to fight them, rebellion efforts died off, attention turned elsewhere.
In the decades since, the dam has become an important representation of Medimia's ability to influence its local and political environment. It stands as firmly as it ever has, with the occasional attempt to take down its walls ending in tragedy for those who attempt it.

Only nature's own disasters seem able to topple the dam at this point; indeed, flooding in the early 5610s saw the reservoir nearly reach capacity at some points, and particularly harsh winters have seen cracks form in the dam itself. Those who fought to end the dam hope that one day, nature will do their work for them.
An interesting conflict. I always side with the rebels and revolutionaries in such arguments, but understand how they might not have had the numbers and ability to keep up the fight. Well and the will. Cause definitely sounds like they were up against it from the outset, a large gap in the capability and power between the two sides noticeable, which would make sense. Well written Han, I like it very much!
Yeah, there wasn't really any chance they'd win this. Trying to fight against one of the largest and most oppressive empires in Istralar currently (though certainly not historically) wasn't gonna go well for them :') Not when Medimia left morals somewhere far in the past! Thank you!
