Some notes about this...
There are still a few things about this quest-line I would like to clear up. First of all, I included the (From __________) part after the quest names for a certain reason. It is important that when you accept a quest from any of these people, you accept it in the corresponding location. For example, if you finish "The Great Forest" from OakHeart in the Tree of Life, in order to get the next quest in the line, you must talk to OakHeart in the SAME PLACE.
If you finish questing with MossBack, there will be NO HINT telling you to then go to WaveBringer.
There are more things I would like to say, but my mind is really going blank now.
If you have any specific questions about this topic, please leave a comment here or email us on the Ask a Question page. I think it is pretty simple if you take it nice and slow. Slowing prevailing. Kinda like the Ice School belief...
Hope this is very helpful!
