Vaelyn says the Core is opening but we can't see it, can we?
If you have been doing the mission "Dreams and Nightmares" for the radiants you have probably noticed that there are some suspicious pipes here and there . What are they doing there? They are parts of the Core's hatch, which has been placed incorrectly (or not)! The hatch is shut down and apparently it cannot be opened.
Has Vaelyn lied to us all? She says the Core is opening, but the hatch is still shut. She says the Core is opening but then she says she's still trying to find means to open the core .
But the big question is: Has the Core's hatch been placed incorrectly or not?
