Hearthstone is about to release Voyage to the Sunken City, its first expansion in the Year of the Hydra. This card set takes players deep beneath the oceans of Azeroth to the ruins of the ancient empire of Zin-Azshari. Now known as Nazjatar, the sunken city is home to gargantuan sea monsters, ancient secrets, and the mystical naga ruled by Queen Azshara. Each card coming to Hearthstone explores these forgotten depths with new keywords, art, and atmosphere.
