It’s looking likely that the story of World of Warcraft will jump forward in time following the events of Shadowlands, based on NPC dialogue in the alpha build of the upcoming Dragonflight expansion.
As documented by Wowhead, two conversations, one on the Horde side and one on the Alliance side, point towards “several years” passing between the end of Shadowlands and the beginning of Dragonflight, despite the “end” of the Shadowlands story having only taken place a few months ago following the release of patch 9.2. If you don’t want potential story spoilers, best turn back now.
In Stormwind, human leaders Genn Greymane, Mathias Shaw, and Turalyon talk about the state of the Alliance, with Shaw mentioning the time skip and the fact that the king of Stormwind, Anduin, has not yet returned following his departure at the end of Shadowlands. Turalyon, it seems, is ruling the Alliance in his stead.
