"Exactly. No future actions, but it also means we have to keep to ourselves as much as we can."

Philip taps his head. "I have nearly the entirety of human history uploaded in here. There were smaller things along the way but the big mission we had been working on was an asteroid impact. It would trigger the events that led to the global collapse. We managed to avert it but we were waiting to hear from the Director what new changes it brought."

He shifts on the sand. "Historians... sometimes we get updated. It's dangerous. Really dangerous. Sometimes it kills us. But we get updated with the new timeline, new information, changes since we landed in the twenty first. It causes some pretty serious side effects. It's a last resort sort of thing. If we enact another major two or two, I'll probably be contacted about it. If I'm willing to do it."
