Nice one, a bit of idle chatter between Ammy and Muse
So Red Muse used to be red? I didn't know that.
Slaveless, all I can really say is that you should go back and read about the character. The more recent bits, after Anni joined, shows the more mature Kix. I think you've done ok mostly, except that Kix isn't really interested in technology.
The story of Nova, was that he and Anni were best friends in a lab they used to work in together, and then one day the vykkers grabbed them and strapped them to a machine to do a wierd brain-swap experiment or something. I can't really remember all the details, so I'll probably have to go back and read about it myself. Anyway, it seems that Nova's mind was put into Anni's and he occasionally takes control and gets rather violent. When he takes over, she can use spiritual powers as well, like calling up fire.
Anni explained it to Stivik when she was trying to reason with him. I'll try and find it and post a link somewhere.
