Bayyuralar (concept)
Bayyuralar, meaning Western Journey in Archaic Kolrgiian, was an invasion of Aironoi by the Baytor, the last Kagakhatan of the Otachedian Empire
The ill-fated expedition began shortly after Baytor's victory in the War of the Five Brothers, where he slew two of his brothers, exiled one, and turned his elder brother, Mogha, into his bondsman. While the war was brief and left Kashirya mostly undamaged, it was the first collapse of Otachedian authority and inspired the first rebellions against its rule by the native Kashiryans. With Kashiryan scholars publishing anti-Baytor tracts at the behest of his aunt and his rivals in other Otachedian kingdoms, and even his own Öltenic vassals and clansmen questioning his right to rule, Baytor decided to invade Aironoi to both secure new lands and to establish himself as the true successor of Otached's legacy. He famously declared the expedition west would cement him as being greater than his deified grandfather, Otached, leading to four attempts on his life and riots across a dozen Kashiryan cities.
Despite this, he carried out the invasion and fought great successes in eastern Aironoi. The largest movement of Öltenic soldiers and clans since his grandfather's invasion of Kashirya, the Otachedian armies were well-supplied, trained, and spirited for a new war. Morale was noted by contemporaries as being exceptional, as the generation that marched west believed they were given a chance to earn the glory of their grandfathers, something their own fathers were unable to achieve. These successes did not last long, and were likely gained as a result of the eastern realms being unprepared for any significant wars of this magnitude. When the horde marched west into the Astilik Empire, Baytor was thrown off his horse and drowned at the Battle of the Wall of Astila, leading to the end of the Otachedian Empire and the establishment of multiple Öltenic warlord states in Aironoi.
