Two questions if I may. 1. When I try to explore Orobas Fjords, I seem to be blocked from going to certain places.Why? 2. I have a lot of ingredients, and scrolls, and books and such, but where can I find an alchemist?
There is a barrier blocking access to the full fjords until after you have the battle tower (you need the dragon form to be able to get to where you need to in order to lower the barrier).
Before getting the battle tower, there is an alchemist in the starting town in Broken Valley. Check the miller's cellar...
The key to the cellar is in the kitchen, in a pot covered by some vegetables. You can mindread the miller for a clue to its location, but it will be there regardless.
