How do I continue the northcrest's conspiracy?
From what I see in your quest logs, you need to talk to Everett about Gunnar (this is an importance part of this event and I suggest you to save your process before you choose a choice.)
Nothing happens when I talk to everett.
Have you talk with Scar about Cove Exploration?
I did.
And what happen to him now? Is he just disappear or stay the same?
Nothing happened. I still have the same quests: war, and northquest. It wont let me upload an image.
