Um, I broke the crystal in the fairy forest, and the only thing that happened was a fairy who originally did not want to fight attacked me. What's supposed to happen? It literally traps me there every time I do it, so its the farthest I've been able to progress. I'm going to try the other route now, but why can't I break it and I actually gain the ally, the door opens, something?
I found nothing in the game files hinting of this "powerful ally", so I couldn't tell which file was assigned to her. There is an animation for the gate opening, but I cannot tell how to activate it. I know its not the end because I haven't seen even half of the characters and I'm already four hours in on my save file.
Edit: I took the other route, and it works fine. However, both options should be available, and since one seems broken, I cannot do anything with it.
Oh, one issue. With all the grinding I did to get through Arashia forest easily, Xeoclat Hills and the fairly forest was seriously lacking in difficulty. The boss in Xeoclat Hills was faster to beat. Too bad I couldn't do much grinding.
