From someone who has not yet read all the books I have no idea from which lore from Toussaint comes from the novels. Then, all my expectations come from what CDPR has put in the in-game book named "Toussaint, a Duchy out of Tales of Fantasy and Wonder"
Based on that, expectations are the best! Expecting to see:
- A vibrant, beautiful landscape such/even better as the Northeast of Novigrad; Lots of winery of course; Rich folks, perhaps some lords riding carriages; Curious to see how they will react to the Witcher.
- Lots of bards performing across the lands/villages/taverns; Without being bothered by witch hunters etc; More scholars too;
- Elven dungeons beneath the main city;
Also I'm curious to see what is the "ancient bloody secret" previously announced, since the place really seems to be exuding richness and happiness; Also, which kind of contracts/foes will Geralt have to face, as the place looks not dangered at all;
