Can't think of anything off the top of my head, Symbaroum tends to introduce its secrets slowly and across the Throne of Thorns books. I didn't let my players read the main book, but that was mostly because I was starting with The Promised Land, and had all the characters be from the ruins of Alberetor, so they could discover aspects of the setting once they crossed the mountains.
Regional breakdowns in the Core don't really contain anything that someone actually living there or from there wouldn't know, if I remember rightly, and Wrath of the Warden is centred on Thistlehold and its immediate environs, you'll know a lot more about this than your player, because you'll have read both the core and the much more detailed information on the campaign book.
