The first big location that you gain access to is the Hinterlands.
Unfortunately, not all of the Hinterlands will be available from the very beginning.
Some of the areas in this location (e.g.
the Redcliffe village) remain unavailable until you complete some of the main quests.
Therefore, it is better to leave the exploration and ultimate “securing” of the area for later.
In the meantime, you will gain access to Val Royeaux and several bigger optional locations.
Apart from that, it’s possible for you to also visit The Forbidden Oasis.
This will prevent (SERIOUS) problems with completing such a quest.
