Iorne Seld (concept)
The Iorne Seld, or 'Sword of Eons' in the Öltenic languages, is the legendary sword of the Öltenic warlord Otached, who united the Öltenic clans into the Iorne Horde and brought them south to Kashirya after the Khayar Seldnii Darn and its clash with the almost as legendary blade Eyon Faeng during Otached's duel with the Kathuni Xaoi Yaung Zayang, which caused an explosion that destroyed the state of Cheyyungjei. The sword was of utterly unknown make if tales are to be believed. Otached is first to have discovered it after slaying a great dragon, whose gaping maw opened a portal to a distant realm, from which Otached pulled the legendary sword and beheaded the beast, forever sealing the portal.
Despite some doubt from Aversarian scholars about the veracity of the sword, the tale of the legendary blade seems to predate that of Otached's discovery of it, leading to a plethora of conclusions from the belief that Otached faked the blade to legitimize his rule to the possibility he truly did find an ancient sword that had already entered Öltenic legend. Öltenic mythology claimed that the sword was the blade of Ölik, son of Ölgon-ten, chief god of the Öltenic pantheon, who came to Aeras as the first human before being killed by the earth goddess Yeru-Mai. Whether the true blade or fake, its finding or the belief in its authenticity allowed Otached to greatly legitimize his rule and was instrumental in his unification of the Öltenic clans.
The blade passed to his son Ayran in the later Otachedian Empire and then to his son Baytor, who led the Öltenis west into Aironoi during the Bayyuralar, where he drowned in a creek after being thrown from his horse, the sword being washed away into the nearby river and then to the sea. While many Öltenic nomads and Aversarian explorers have attempted to locate it, the location of Baytor's death has become lost to time, and the veracity of the sword has remained in question.
