Iorne Horde (concept)
The Iorne Horde (or Eonic Horde), was named for the legendary Iorne Seld, which was used by the Öltenic warlord Otached to unite the Öltenic clans after Khayar Seldnii Darn. While not victorious in his wars, that destroyed the Kathuni state of Cheyyungjei and wiped out both the Öltenic and Kathuni armies, Otached yet proved to perhaps be the most shrewd propagandist and statesman in Öltenic history, and he managed to spin his survival as proof of his descendence from the god Ölik.
After uniting the Kolrgii Steppes, Otached marched south, away from Kathun-Kai. Öltenic tales say he had grown bored after defeating Xaoi Yaung Zayang, the mightiest of Kathun-Kai's warriors, while Kathuni historians wrote that the wars devastated the steppes just as badly as Cheyyungjei, and that the clans could not survive another war of similar scale with Kathun-Kai's largely untouched eastern armies. The truth is unknown, having occurred before even the birth of Wardenism in Sarradon, but both accounts are commonly accepted to hold some truth.
Otached led the horde south and into Kashirya, smashing the struggling Varodaist kingdoms and conquering down to the modern Pirate Coast. The Horde was disbanded thereafter and was followed by the Otachedian Empire. Despite its short decade of existence, it greatly affected world history. The closing of the Öltenic-Kathuni Wars and the Khayar Seldni Darn reshaped Kathun-Kai, while the conquest of Kashirya established its first true empire. The unification of the clans gave rise to all following Öltenic cultures and religions, while the Otachedian Empire and its successors greatly shaped the history of Aironoi and the Aversarinas Aautokrata.
