Hearthstone’s next adventure sure looks like Karazhan

Blizzard is getting ready to send Hearthstone: Heroes of Warcraft players on a magical, new quest.

Earlier leaks suggested that Karazhan could be the next adventure for Blizzard’s market-leading digital card game. Now the company has sent out invites for a Twitch event on July 28. The invitation has several decorative feathers, which give more weight to the whole Karazhan thing. Medivh, a sorcerer known for turning into a raven at will, is the most famous master of the magical tower. Hearthstone makes $20 million a month, and it’s the leader in the $1.2 billion digital card game segment. New content ensures that players are engaged and more likely to spend more money.
