So I have a a theory going that finishing the VoG wasn't actually part of the story. When you fly to the reef for the first time, Petra mentions that you have defeated the Black Heart, and Crota, but she says nothing about the VoG. Later in the story, we go "back" to VoG, but the oracles are still there. If we really have defeated the Templar and Atheon, shouldn't the oracles no longer exist? Feel free to comment what you think, I'll try to answer everyone. Also, forgive spelling, this was written on a phone. Edit 1: Guess nothing can be explained with time travel involved. Now another point to raise. We don't know how long the fallen were in the well, but they seemed to have set up shop there. So, why did the oracles not spawn until a guardian arrived? Does this mean that the Templar/Atheon "remembers" us? Also, was Skolas able to harness the power of a random vex in that last mission, or was he deeper in the vault while we were fighting in he well, and harnessing the power of Atheon himself? Either way, I'm really enjoying this story that raises so many questions.
