How much do Giants know about Felarya?

Isn't the Fairy Kingdom to the west of the current map and not to the south? The south leads to the Dridder Forest, which used to have repertoires of knowledge, but has since fallen apart following the abrupt end of Sineria's reign.

I still find this far fetched. How often do people from Negav even make it close to the extremities of the current map alive? What are the odds of predators from the Great Rocky Field or Akaptor Desert or the Ixtapal Marsh to make enough contact from people of Negav to suddenly become aware of the city's existence, let alone the name of regions? For regions that neighbor Negav like Chidokai Forest, Ascarlin Mountains, Dridder Forest, and the southern parts of Tolmeshal Forest, that makes sense, but past that, then I would have seriously doubts that it would be common knowledge. Again, Vivian and flying predators not withstanding, unless they stick to their regions far away from Negav.

The Fairy Kingdom I also have problems with. It's more or less isolated from the rest of the world. Sure, there are bridges, but like the wiki says, explicitly too, the best way in and out of there is by flying. And like I explained in a previous thread, I find the concept of fairies instantly being buddy-buddy with anything that's too big to shrink very cliché and a lazy way to handwave nonsensical concepts.
