My visitors have voted, and the results of the Kyn Poll 2009 are:
Richard & Elíane: 13
John Keller: 10
New characters: 8
Nick & Gabriel: 4
Kyan & Melanie: 2
Thierry & Jema: 2
Any character: 1
Richard & Elíane are the clear winners, so the next Darkyn free e-book will feature a continuation of their storyline (which should be really different from what I've done so far, as well as a decent writing challenge for me.)
Since Korvel came pretty close to tying R&E for the top spot, I thought about having him as a secondary character in the e-book. But honestly, I think Korvel needs his own novel-length story to resolve his issues. I had tentatively planned to feature him as a protagonist in a future Darkyn print standalone (the story would probably include Nick and Gabriel as secondary characters doing what I had Nick and Alex discuss in STN) should that ever come to pass. I don't know right now; I'm going to give it some more thought.
Thank you all for the input. It really helps me to hear what you're thinking and what you'd like to read in the future.
