Karazhan: A primer for Hearthstone’s (fingers crossed) next adventure

Recent leaks hint that Karazhan will be Hearthstone: Heroes of Warcraft’s next adventure. This story is for the people who don’t really know what that means.

Hearthstone is a digital card game behemoth that makes over $20 million a month. It’s able to keep players engaged because it regularly releases batches of new cards, alternating between expansions and adventures. Expansions add a lot of new cards, while adventures add fewer cards but also give players story-driven, single-player content.
