Blizzard Entertainment has announced its latest adventure for Hearthstone: Heroes of Warcraft, called One Night in Karazhan, will be available on August 11.

Blizzard announced One Night in Karazhan earlier this morning, which is being described as the hottest party in the Eastern Kingdoms as players will enter Medivh’s tower, Karazhan, to take part in a completely enchanted experience filled with lavish feasts, Opera performances, and more.

Unfortunately, when you arrive at Karazhan, you’ll find Medivh is missing and his collection of arcane objects have completely run amok throughout the castle. You and Moroes, Medivh’s buttler, to not only attempt to find him, but to also keep the party under control while attempting to find time to enjoy yourself.

“One Night in Karazhan will give players the chance to party with Medivh while earning some great new cards for their collections,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment “We’re excited to reimagine one of Azeroth’s most beloved locations in Hearthstone, and we can’t wait to see players put their new decks to the test.”

One Night in Karazhan will introduce 45 new cards to Hearthstone when it launches on August 11 on Windows, Mac, iOS, and Android for $19.99 for all four wings. Those who want to purchase each wing with gold or a smaller price, you can spend 700 gold or $6.99 for each wing. Those who are curious about the new adventure can partake in its prologue for free, which will net you two new cards. Hearthstone players who purchase the full Adventure during its week of release will receive a special Karazhan-themed card back.
