I know what you mean, I wrote one Ash/Vaysh (just a one shot) set well after the whole thing but I still couldn't bring myself to make it an actual resolution, I just didn't think I could do it justice.
I love that Storm has created this virtual playground for us to run around and go crazy in, there really is no limit within this world because original characters are so welcomed. It's so awesome that she is still writing Wraeththu novels with new characters etc, and even more wonderful that she encourages everyone else to.
