Curse of the Crimson Throne
Korvosa is the eldest of Varisia's three city-states, once part of Imperial Cheliax but now independent. The settlement originally served as no more than a defensive position from which settlers and explorers would enter Varisia, only growing into the cosmopolitan center of trade that it is today with the passage of time and events.
Before the arrival of the Empire of Cheliax, Korvosa was no more than a site sacred to the Shoanti; the protection of the location, as well as the pyramid found there, was of great importance. However, in 4407 AR a group of Chelish marines under the command of Field Marshal Jakthion Korvosa selected the site to begin construction of a defensive outpost. Once completed, Fort Korvosa acted as a common stop for explorers, settlers, and trappers operating in the region. The trading post and its defenses were later strengthened after a Shoanti raiding forced burned much of the location in what would become known as the Great Fire.
The Cousins' War
The Cousins' War began in 4502 AR, the result of an insult directed at one of Korvosa's noble families. The conflict heralded the end of the settlement's significance as a military position, but also resulted in the growth of both its population and economic power. Soon after, Korvosa was seen as a true colony of the Empire of Cheliax.
Death of Aroden
In 4606 AR the death of the deity Aroden resulted in civil war in Cheliax; many of the Empire's colonies, including Korvosa, suffered as their connection to the homeland unexpectedly disappeared. The city's government has succeeded in achieving some measure of prosperity since the Empire's decline, but the city's recovery from the chaos that resulted as a result of the Empire's sudden absence has been slow; its population is but a fraction of what most would expect given a settlement of Korvosa's physical size. Nevertheless, regarding political power, Korvosa is now equivalent with Magnimar, though this is far below the level considered appropriate for its decadent ruling class.
