Scien mentioned something about ... magically copying sets of memories, to perhaps combine them with the ones you have and the ones of the timeline we are heading to. A modified Soul Jar perhaps could do it, I don't think it would be too profoundly difficult. Or at least, not for me.

Since I am from the earliest point, perhaps my timeline could be used as a chance to correct any mistakes you think you may have made along the way? Foresight can be terribly useful.
