What happened to Cynder?

[Thomas]

So...my thought at the time was that Orcus would kill Cynder and bring him back as some sort of undead dragon. That's still the most likely outcome, but I haven't had time (or a fitting way) to show that and bring undead-Cynder back into the stories. I do not believe that every single secondary character, no matter how cool or fun, must reappear; I use them when it seems right. With hundreds of such secondary characters, it's hard to show what happened to everyone.

Having said that, I do think we'll see Cynder (and Orcus) again. I'm just not yet sure exactly when that will be.
