That's not so simple to explain, sorry

!
The best thing you can do is go futer explore the Orobas Fjords. Look everywhere you can, because there are a few "hidden" locations ... I mean by "hidden" .. when you're in Dragonform, fly up and down and search everywhere along the mountain walls!!
And if something attracts your attention, check it more closely and change back into human ... but watch out for enemies!
Good luck!
What I do: I explore and explore whole the time and so I find all the quest-items at time ...
