This is what it's about.

RoseThorn tells the story of the Adanae, a people of extraordinary beauty, intellect and power, a people with a past and a secret hidden even from themselves. Twenty-five generations ago the Adanae were exiled, cast on the sea in seven ships and driven before a terrible storm to land on the shores of a strange land. There the Adanae found only primitive tribes, still with merely stone tools and weapons. And the tribesfolk did not have the Mahare, the magic that the people of Adan drew upon for their power. A few of the primitives befriended the Adanae, but most fled away from them to live on the edge of survival. The Adanae began to build a new city in the wilderness--Adan.

The crime committed by the exiles would remain hidden, for after landing on the new shores the Adanae fell under two curses: the Ban and the Forgetting. The Ban forbade any Adanae to ever sail beyond sight of their new lands. The few that defied the Ban perished in violent maelstroms that assaulted their ships. The Forgetting afflicted all of the people of Adan, causing them to lose all memory of who they had been or why they suffered exile.

Twenty-five generations passed and the city of Adan grew along the River Edara, a city of marble and granite, of temples, theaters and markets, parks and gardens. The Adanae poured the Mahare into everything they built, and the city grew, radiant and graceful, a city protected by a Wall that could never be breached. Within their city the Adanae became great again, a people of culture, of learning and art and philosophy. But as wondrous as they made their city, the world outside remained as it had been, wild, primitive, and brutal.

Untouchable. Unblemished. So the Adanae thought. But dark forces gather over time, and even the strongest may fail to weather the storm if caught unprepared. This is where the story of RoseThorn begins . . .
