If you''ve talked to everyone try going to the forest. That's normally the next destination.
That's the kind of a subjective perspective you really shouldn't force into the game because what might a no-brainer for you isn't for everyone. And without a quest-log, it's a pain figuring things out.
...Plus it didn't even work for me. At least, I'm meeting the same 2 characters in the forest, and even after dozens of attempts and regardless of how I interacted with them, I got nowhere. I've literally circled through the map close a dozen times, speaking with everyone about every subject and couldn't progress still.
I think I'm just gonna let this one go, at least for now.
