Not off the top of my head, no... before this, I've never heard of a universe, any universe, where the entire timeline's been one huge fixed event. It just doesn't fit my world view, more than that, it doesn't fit everything that I've ever understood about time. All those fixed points and flux points, I can feel them all if I let myself, it's instinct, and imagining a universe where it's all fixed, it's..... Without at least going there myself first to get a real feel for the timestream, I wouldn't want to risk trying interfering with something like that.

It's a long shot - a very long shot, mind you, so don't get your hopes up - but the only thing I could think of that could possibly change things without causing more harm than help is if the community was involved. It's a point of chaos that manages to influence that world outside of its predestined events and even throw Doc Scratch for a loop. If there are any answers to be had, I'd say we'd find them there, but it's all too tricky to say anything for certain.
