Twanwey [twan ˈwej] was an emperor of Uytai.
He was in power during the final collapse of Krwŋ due to ecological devastation. This caused problems for Uytai, as Krwŋese attempted to migrate to more fortunate lands to escape starvation; at first this was allowed, but they soon became too numerous and the Uytainese turned them back at the border.
However, the opportunity was clear to recapture Uykhrai, the former capital taken by the emperor Susirn in 1457 (largely through the treachery of his cousin Nyanyar, wife of the Uytainese emperor Tyaisut). In 1684 Twanwey mobilized his armies and reconquered the city. (The Krwŋese had recognized Nyanyar's contribution by erecting a statue of her and of Susirn near the main palace. Susirn's was melted down, but Nyanyar's statue was gleefully placed in a public urinal.)
And why not continue to take the rest of Krwŋ? Twanwey moved north, occupying the city of Twot. But he could see for himself the destruction and misery of the country. The Krwŋese would offer little resistance; but dealing with such poverty and misery would be a great headache. He called off the war, and erected an inscription at Twot praising his own mercy.
His recapture of Uykhrai reversed an old humiliation and was long considered a high point of Uytai, especially in the darker times that followed. He was sometimes called the "last wise emperor", and especially revered by the Hanthal dynasty which took power in 2031, as a rebuke to the former dynasty, which had sometimes ruled more territory than Twanwey, but supposedly with weakness and corruption.
