Rau Xengi [ˈraw ˈsɛŋ gi] is a province of Xurno comprising the upper Xengi valley. It borders non-Xurnese territories on three sides: to the east is Mei territory; to the south lake Van, and to the north is Cuoli. Downstream is the province of Šuzep.
The province has its own dialect, Lejur, notable for the emergence of a long/short vowel system (the long vowels mostly replace diphthongs in the standard dialect), and for the raising of final -a (e.g. pija is pronounced pijɛ).
The province is by no means a backwater, but its inhabitants are considered unsophisticated, though not so much as people from the outer provinces. On the other hand, they're also considered straight dealers and friendlier than people from downstream. The area is a natural conduit for trade with Belšai and the Lenani, however, so it's not as culturally homogenous and self-satisfied as Šuzep.
The region was settled by the Wede:i; Sieš (then Saiśi) being one of the earliest city-states (c. -1200). It was conquered by Begoŋitera of Yenine in -650, and then by the Ezičimi in -325, and subsequently passed back and forth between Wede:i and Ezičimi for some centuries. It was not till the 860s when the Axunemi under Timai permanently absorbed the region, then known as Moun; its capital was the city of Neiral on the Puro.
In the 1600s Munkhâsh made a play for continental domination. In Xengiman they offered an army to the emperor Bijereis, who was embroiled in a civil war, on the mere condition that he build a temple to Gelalh in Weinex. Bijereis rejected the alliance, but the governor of Moun, Neirimi, acccepted it (1635). Neirimi was able to conquer Šuzep, Rajjay, Bozan, and Gotanel-- more than half the empire; Bijereis was restricted to the delta and Tanel.
Unfortunately for him, Neirimi had chosen the losing side in the continental struggle. The Munkhâsh withdrew their army when the Kurundasti Tej invaded Tyellakh (1645). The provinces he had conquered rebelled; his enemies invaded. Neiral was burned, Neirimi and his recently completed temple of Gelalh with it (1648).
The unity of Axunai was lost, however. Moun province was ruled by Tanaza for awhile; most of it was conquered by the Tej in the 1730s. Minor Axunemi states divided up the region after the Tej weakened, two centuries later. The most important local power was Rašageor.
During the invasions of the barbarians, the region was occupied by the Sainor. The new nation of Xurno pushed the Sainor out in 2690-2720. During the Revaudo civil war, Cuoli inherited the principality of Van and conquered the upper Xengi which separated its two territories. Cuoli however overreached when it attempted to conquer Belšai, and when its empire collapsed the Xurnese were able to regain the upper Xengi (3240-60).
