The Pestilence

Plague / Epidemic

On the 29th of the 5th month of -399, the demolition of the Tomb of Arzagoth, then known as the Burning Rock to nearby villagers because of its mechanism that generated flames to appear at the top of the structure, was ordered. As soon as a new room of the tomb was pierced, a spray of pressurised air jetted into the workers' faces. This was the starting point of the infection, as all the air in the tomb was contaminated with a deadly necroting virus that targetted elves.
In a matter of month, the entirety of the Empire was infected. Within a year, half of its elven population was either bedridden or dead. After two years, all of the Empire was dead, either from the war or the disease. On the 3rd day of the 8th month of -397, the Empire was declared vanquished.
