On March 17, CATACLYSM descends on Hearthstone, bringing back the fan‑favorite destroyer, Deathwing. Only this time, he’s not the Worldbreaker you remember. In the final moments of Across the Timeways, Murozond refused to accept defeat from Chromie and the Heroes of Time, so he smashed the Hourglass of Time and opened a portal to a nightmare timeline where Deathwing never fell. Now this undefeated Deathwing is invading Azeroth with six terrifying Lieutenants, and they’re ready to break the world all over again!
