That's a question I'm asking myself as well to a degree lol. I'd say we're about 1/3 through what I had planned that is actually reasonable to do, give or take a little. Not sure how things will work out in the end.
But the very rough idea was Hieroneiden arc (culminating in deepwoods, yea), hero's journey arc (culminating in Astrologia and finding out what's going wrong), and then an unnamed arc that culminates in the overall finale.
