How do I know where I'm going in the game?

[noja190]

I like the no map thing this game has and how the quest system works. I'm really digging it, but I've been given an objective to go to south karana, and I have no idea how to get there from Kaladim. I just started playing the game and I'm not too familiar with the world. I don't want to go looking up zones and directions online, because I feel like that's not how it was intended to be played, my only question now is, how do I figure out how to get there? Are there NPCs I can talk to? a map I can buy from a shop? Or am I pretty much stuck googling on how to get where I need to go?
