With the upcoming changes in patch 3.0, all players will gain access to “Whispers of Oblivion,” a three-mission prologue featuring the legendary Dark Templar Zeratul. These missions serve as an introduction to the campaign, and help bridge the story between Heart of the Swarm and Legacy of the Void. In Whispers of Oblivion, players will take part in the story of Zeratul for the first time since Wings of Liberty. Therein, they’ll seek to unravel the final piece of the Xel’naga prophecy.
