While watching some old media coverage, to get a feel for how they deliver information to us, there was something I noticed. Heavensward aside, since I guess they were still figuring things out, each new zone preview has been shown with its respective music, with one exception. During the zones for Shadowbringers, when they show Il Mheg, the music that plays, at least to start, is the town theme, then it transitions to the normal theme. The bgm for Labyrinthos could be a similar hint. The moon has some significance, but I wonder if the last zone is truly there. We'd expect it, so maybe its not, maybe it's somewhere entirely different.
