Krán found the growin power of Pyarron unsettling, she learned from the previous exchanges with the Demonic Old-Empire and Godon so she launched a pre-emptive strike.
First they managed that the Southern Nomads chose a Great Khan over all the tribes, it was in 3672 AP. Next year the nomads attacked the Pyarronite Commenwealth from the south and gave them a good thrashing. Two years later the Pyarronites gathered themselves and won a flawless victory and began to chase the nomads out of their lands.
Then came a big punch from the West. Krán herself sent Orcish hordes from the mountains and destroyed everything in the Valley of Dorlan river. The chasing armies turned around but were beaten and disperesed. At the end of 3674 AP a provincial legion from Krán and some Aquirs arrive through a portal to the walls of Pyarron city. They destroy it and kill everyone.
However quarrels erupt over the loot between the Orcs and nomads this divides the attackers. The Chei, king of Yllinor, won some battles over the nomads, and finally (four years later) help arrives from other yet untouched Pyarronite states (e.g. Six Cities) and Shadon. These forces with mercenary companies from all over Ynev and irregular units (formed by the remnants of the destroyed armies) liberate the lands by 3685.
The city of Pyarron transforms into a big cloister and the capital moves into the river delta of the Dorlan. New Pyarron was born in 3691.
