Yep. I did enjoy Past Sins. It inspired me to write Black Feather because I really felt that someone needed to finish Nyx's character arc. And now... I'm really fortunate that my story has inspired such a good artist like BDK to draw up the first chapter with this comic!
You're always welcome to read the actual story the comic is based on, of course. Links provided in each comic page posting. The comic will only cover chapter 1 of Black feather, but the story itself is far, far larger. This is just the tip of the iceberg.
