That seems like something which may very well tie into the next bit of the game’s main scenario questing, since players have been told to expect the return of a major character. But the preview page sounds a bit more ominous, noting that change is coming to Ishgard while obliquely implying that said change may not actually be focused upon the revelations about the Dragonsong War. The patch will be arriving on February 23rd, but you can feel free to speculate on what happens next until then.
