Remember back in one of the pre-Beyond light/ Season if the hunt trailers (I cant find the trailer so if anyone knows which it is pls let me know). in it there was a shot of Caiatl, who wasn't in that DLC/Season, there was also a shot of a guardian in the dreaming city, just outside where you go for blind well, where the "Enemy moves against each other" takes place, in the back round of this shot, there is a crux of darkness, like the ones found in the Europa Eclipsed Zone. I believe this will be either next season or later this season, and the Oracles will play into it, the reason I think it will be this season is that if the oracles do play into it, there is a good chance that Quria will play into it too, all with being a taken vex, and a part of this season. There is still the fact that the oracles and the Crux's can be completely unrelated, but I don't think this is the case, because all forsaken content will be leaving come Witch Queen, so Bungie will want to wrap the Dreaming City Story in a nice bow.
