Re: Task: The Watchers Problem
Half of Eos is locked until after you go to Aya for the first time. I think watchers and ghost of a promise both use the extra area. I don't know about fast traveling or leaving the planet, neither helped me with watchers, I still had to go to the last camp. It may be possible to get all the items without leaving or fast travelling, I know it worked like that for me on Voeld with similar quests.
