Honey, you get the impression most people is Restov only know basic information about the stolen lands. You get a lot of shrugs, and mutterings of fey and using cold iron against them.
The area is quite a large expanse so the terrain changes to a degree, but the area you seem to be heading to is mostly plains and hills, with some forests around your destination. There is quite a lot of rumours of bandits, fighting over scraps of the land in hopes of being some sort of false lords of the area. The closeness to the feywilds also lends itself to quite a few magical beasts.
As you are finishing you information gathering you run into an older man who seems to have been enjoying a few too many drinks, all seems all to happy to fill you in on various stories.
'Y' know, the Taldan's tried t' conquer the place, but t'was too much fer t' greedy bastards. Though not the fey, no no, that's what they want y' to think. There was a bigger kingdom, the kingdom of the ages. Biggr' than Thassilon evn. Tho' hubris took it down, but still it won't give up it's clutches on the lands.'
Those nearby hearing the mans tale roll their eyes, clearing seeing it as nonsense.
