We've all seen the videos and we all thought they were ahamakara and we all found out Bungie wasn't actually planning to do anything with them. But I just have a few ideas about the vex and the "dragon". This is just some interesting ideas I came up with: -We all know the black garden is where the vex originated from and the heart is in control. But could there be something before it? What if some bigger, more powerful race created the vex, and/or the heart to make them to fulfill their plans. -Could it be possible the "dragon" creature could have anything to do with the vex? Maybe it is just another type of a vex, or maybe it is more powerful than we think! -When Kabr's firearm went into the vault, and didn't return, perhaps the vex could have stolen them and changed them somehow maybe adding them to the vast network and understanding of time and space. Anyway, those are some interesting ideas I came up with about the vex. The dragon probably won't be in Destiny as Bungie claimed it was just a "betadactyl" but it's still fun to think about and make assumptions.
