Maybe, so the 4 files (that I didn't read) above is for purchase. It has Aqua Mortis, Park Pale, Alone in the Crowd, and Playthrough examples. But the main Solitary-Defilement book, we use the free version for download above? I think the confusing part was I was looking for the title "expanded edition", but the title on Solitary-Defilement.pdf (2nd page) says "first" edition. If so, updating that little piece would be helpful! Looking forward to playing, thanks for your efforts!
