Sooo, Valdis and Kylo and the Cultists, right? And Kylo needs influencing towards the dark side?

I think we can work with that. Also, I might have a temporary solution to Valdis' problem that Kylo can help with. :P

Starting with the Cultists, how exactly would he try to convince Valdis to let him 'help'? She's hard to fool but I'll bet we could figure something out. She could pretend to believe him, or she could begrudgingly allow him to help for some reason. Maybe tries to manipulate him into getting information for her. That might toy with his dark side a bit.

Due to her issues with the Void, she might actually act more like who she used to be as it chips away at who she is, something I find very interesting and it could be fun to explore. This might apply to Kylo as well because they could inadvertently feed each other's darkness.

Also, if Kylo wants to 'Destroy' Valdis, I am totally down with that. In fact, she might purposefully push him to do that hoping for a 'reset', which could give her temporary relief from the Void, except it doesn't and that could also be fun. Plus, Kylo would get to see more of her power, namely the resurrection portion.

And I'm going to stop now, because wow I have a lot of ideas. :P
