well it wasnt me who asked the question. but you replied to it.
"Garan Elderan
The game has so much extra content that the history is lost within... I'm already completely lost in the game, to the point to not remember anymore what I was doing in the last update. If the game has a better quest log or a journal that points where you are in the main story, it will be a lot better..."
how i understand this is that they have forgotten what they were doing since the last update and want to know what they were doing and where to go from here. illumi can not tell you where you are in the story but she can tell you where you should be going to. like when you finally get to the desert region "you should go and find a way to explore the sealed tomb" or however it was said, point is you should go do X next.
the closest thing in the game right now to help people know where they have been would be the quest log as far as i can tell.
