I'll be the first to say, I love the appearance and atmosphere of Gridania, but it and the Black Shroud are way too maze like and repetitious.
The Poem given to us by Yoshida seems to hint that some things will be destroyed in the future and a time of turmoil will start. I know I'm not the only one hoping that means someone sets a forest fire.
I wish it was a little bit more like San d'Oria then Crawlers nest to be honest :/
