C. J. Cherryh - Well of Shiuan (Morgaine Saga, Book 2)

Last of all only the woman Morgaine survived, skilled in qujalin witchcrafts and bearing still that Sword that casts to death. Much of evil she did in Morija and Baien, rivaling all other evils she had committed... but she fled thereafter, taking with her Nhi Vanye i Chya, once of this house, who was ilin to her and therefore bound by his oath.

Nhi Erij i Myya, in the Book of Ra-morij

Chya Roh i Chya, lord of Ra-koris... followed the witch Morgaine, for his cousins sake... but Nhi Erij in his writing avows that Chya Roh perished on that journey, and that the Soul that possessed the likeness of Roh thereafter was qujal , and hostile to every Godly man...

the Book of Baien-an

Seven moons danced across the skies of the world, where there had been one in the days of the ancients. In those days the Wells of the Gods had been open, providing power and abundance to the khal who had governed before the time of the Kings. Now the Wells were sealed, beyond the power of men or khal to alter. Long ago there had been vast lands on all sides of Shiuan and Hiuaj; but the world now was slowly drowning.

These were the things that Mija Jhirun Elas-daughter believed for truth.

For all of Jhiruns young life, she had known the waters encroaching relentlessly on the margin of the world, and she had watched Hiuaj diminish by half and the gray sea grow wider. She was seventeen, and looked to see Hiuaj vanish entirely in her lifetime.

When she had been a child, the village of Chadrih had stood near the Barrow-hills of Hiuaj; and beyond that had stood a great levee and a sea wall, securing fields that gave good crops and pasturage for sheep and goats and cattle. Now there was reed-grown waste. The three parcels of land that had supported Chadrih were gone, entirely underwater save for the boundary posts of stacked stone and the useless remnant of the ancient sea wall. The gray stone buildings of the village had become a ruin, with water trickling even at low tide through what had been its streets, and standing window-high at Hnoth, when the moons combined. The roofless houses had become the nesting places of the white birds that wheeled and cried their lonely pipings over the featureless sea.

The people of Chadrih had moved on, those who survived the collapse of the sea wall and the fever and the famine of that winter. They had sought shelter, some among the marsh dwellers at Aren, a determined few vowing to go beyond into Shiuan itself, seeking the security of holds like fabled Abarais of the Wells, or Ohtij-in, among the halfling lords. The Barrows had heard tidings of those that had reached Aren; but what had befallen the few who had gone the long road to Shiuan, none had ever heard.

The breaking of the sea wall had happened in Jhiruns tenth year. Now there was little dry land in all Hiuaj, only a maze of islets separated by marsh, redeemed from the killing salt only by the effluence of the wide Aj, that flowed down from Shiuan and spread its dark, sluggish waters toward the gray sea. In storm the Aj boiled brown with silt, the precious earth washed seaward, in flood that covered all but the hills and greater isles. At high tide, when the moons moved together in Hnoth, the sea pressed inland and killed areas of the marsh, where green grass died and standing pools reeked of decay, and great sea fishes prowled the Aj. Now throughout Hiuaj, there remained only sparse pasturage for goats and for the wild marsh ponies. The sea advanced in the face of the Barrows and the widening marsh ate away at their flank, threatening to sever Hiuaj from Shiuan and utterly doom them. Land that had been sweet and green became a tangle of drowned trees, a series of small hummocks of spongy earth, reed-choked passages that were navigable only by the flat-bottomed skiffs used by marsh folk and Barrowers.

And the Barrow-hills became islands in these last years of the world.

It was Men that had reared these hills, just after the days of the Darkness. They were the burials of the kings and princes of the Kingdoms of Men, in those long-ago days just after the Moon was broken, when the khal had declined and Men had driven the khalin halflings into their distant mountains. In those days, Men had had the best of the world, had ruled a wide, rich plain, and there had been great wealth in Hiuaj for human folk.

Men had buried their great ones in such towering mounds, in cists of stone: warrior-kings proud with their gold and their gems and their iron weapons, skillful in war and stern in their rule over the farmer-peasantry. They had sought to restore the ancient magics of the Wells, which even the halfling khal had feared. But the sea rose and destroyed their plains, and the last Kings of Men fell under the power of the halflings of Shiuan. So the proud age of the Barrow-kings passed, leaving only their burial places clustered about the great Well called Anlas Crown, that had swallowed up their wealth and returned them only misery.

In the end there were only scattered villages of Men, farmer-folk who cursed the memory of the Barrow-kings. The old fortresses and burial places were piously avoided by later generations on the river-plain. Chadrih had been nearer the Barrows than any other village wished to be; but it had perished last of all the villages in Hiuaj, for all thatwhich gave Chadrih folk a certain arrogance, until their own fate took them. And the Barrow-hills themselves became the last refuge of all; the Barrow-folk had always lived beyond the pale of lowland respectabilitytomb-robbers now, sometimes herders and fishermen, accused (while Chadrih stood) of stealing livestock as well as buried gold. But Chadrih died and the despised Barrow-folk lived, southernmost of all Men, in a hold that was a Barrow-kings ruined fortress atop the last and greatest rock in all Hiuaj, save Anlas Crown itself.
