Can you share with us what the changes were made? sorry I'm just lazy to read the wn/ln
This ENTIRE CHAPTER is a good example. In the novel Amon died and it was kinda Dan's fault. Details aren't given, but it happened because Dan was jealous because Amon and Marcho WERE together. The Black demon lord wasn't involved because he hadn't even been born at the time.
And the Black demon lord did fake his death, but under different circumstances, after (mostly) different conflict and the result shown here didn't happen.
Literally everything else here didn't happen.
To give proper details, I'd hardly know where to start. I'd have to summarize more than half the novel at this point. The plague didn't happen. The chapter with the cheater didn't happen. Etc. etc.
