Adding in another spice into the pot, with the same dialogue box that everyone is getting "more than a thousand summers" from:



Note that Jenomis says "one of your calamities". One of your calamities.

This isn't the only place people are getting the "more then a thousand years" from. Lore Book 2 introduces Dalmasca this way.

Built on the sands of the Dalmasca Desert to the south of the Skatay Range, this kingdom prospered for nigh on a thousand years under the peaceful reign of the B'nargin royal line. Thirty years ago, however, Dalmasca fell to the Garlean Empire, and the region became yet another subjugated province.

So Dalmasca itself has been around for a thousand years. Meanwhile the capital of Lesalia is so old that the Dalmascans never found it even though it was right under Rabanaster this entire time. If anything Jenomis' estimation about when Durai was alive should be much older then just "a thousand years".
