Oh, I was going to give you details - I would like you to succeed :). Since it seems we live in the same country, I am going to send you a message through Reddit (where I discovered your game), so as not to clutter this page.
I unfortunately couldn't read the tales. Tieulle, Rosette, and Lierris ask me for 150 intestines (!). I couldn't obtain that many, but maybe only because I couldn't find enough places where I could have gathered that many.
Edit: Whoops, it seems I cannot message you through Reddit. In this case, I am going to post the answer here, below. Please feel free to delete it.
