Yes, it was about 1000 years from the Ritual to TC's arrival.
in [u]Lord Foul's Bane[/u] was wrote:"But when Kevin's betrayal had brought defeat and Desolation, and the Land had lain under the bane for many generations, and had begun to heal, it called out to the people who lived in hiding in the Wastes and the Northron Climbs. Slowly, they returned. As the years passed, and the homes and villages became secure, some folk traveled, exploring the Land in search of half-remembered legends. And when they finally braved Giant Woods, they came to the old land of Seareach, and found that the Giants, Rockbrothers of the people of the Land, had survived the Ritual of Desecration.
"Many generations" can mean 5 generations - 100 years - or it can mean much more. My best guess is that this period is between 100 or 200 years.
I don't think that this diminishes the extent of the Ritual. First, that's a very, very long time. Nature recovers from forest fires or volcanic eruptions in about one of our generations. Furthermore, the Land was no where near "healed" when the people returned - in fact, it was so bad, that they eventually pledged themselves to restore it.
in [u]Lord Foul's Bane[/u] was wrote:When the Giants learned that people had returned to the Land, they began a great journey, ... taking with them those people who chose to come, the Giants ended their journey at Revelstone ... At Revelstone, the Giants gave a gift to the gathered people. They revealed the First Ward ...
Then the few who were chosen at Revelstone for the great work took the First Ward to Kurash Plenethor, Stricken Stone, where the gravest damage of the last battle was done. They named the land Trothgard, as a token of their promise of healing, and there they founded the Loresraat - a place of learning where they sought to regain the knowledge and power of the Old Lords, and to train themselves in the Oath of Peace."
Given nothing else to go on, and I don't think that there is anything else to go on, I would say that the time of the new Lords begins approximately when the First Ward is delivered to the people of the Land by the Giants. Which is shortly after the Giant's were re-discovered.
