Not only that, but there's still so much that could happen in Salvation that could affect what I can write.
Salvation isn't entirely scripted; a lot of what happens is improvised and based off of what you guys have your characters do. That affects the story and universe in ways I can't predict.
The only things that absolutely have to happen in Salvation is that y'all find the Omega Lock, and save Primus, really. For most everything else, whatever happens, happens.
