Many of Hearthstone's expansions have roots set in Azeroth. A fan made map shows exactly where we've visited thus far.

Ever wonder where exactly in the world of Azeroth you are when you're playing Hearthstone? World of Warcraft is vast and there are a ton of different locations the Blizzard team has utilized when coming up with adventures and expansions. Miinmeaux, a fan of the franchise has created a map showing roughly where each set takes place.

Notably, a large percentage of the locations are located in the southern half of Kalimdor.
