Discover locations interrogating?

[David Soler 88]

Hi Guys, I know that you can quit the black clouds of the maps interrogating barbarians, and some locations appear, but not all the locations appear, there is any way to discover the rest of the locations? or you just have to explore and walk until you find them? thanks!

Ya more will show up once you explore.

scout camps.
you can see them on map.
all scouts have part of map they'r on.

Also, keep interrogating the same scouts, they will reveal more spots, including tablets sometimes. Eventually though, it will stop saying you discovered anything from them and then it's time to find another scout camp.
