She comes from our timeline. There is a single primary timeline that she loops through iterations of, almost literally like resetting to a checkpoint and trying again. It’s the same timeline, you just reset time back to an earlier point to try again. There are completely separate timelines, the alternative what-ifs that branch from ours, but Elsie is looping the primary. Over and over and over. She’s then able to affect things differently, see what works, what doesn’t and even explore/prepare for the next loop. Saint being saved when he was younger by our guardian helps prove it. Cause lore about the dark futures shows we can go bad or die as early as base D1. So it had to have happened in the same original iteration for to be cemented in, ya see? She goes back to a point long before we are revived yet it happened, despite the future becoming uncertain due to her intervention. It happened in the original iteration. It’s also why Elsie can only go so far back, she could derail things that need to happen in ways she doesn’t know or couldn’t replicate with intervention. I got a visual for you. Think of time like a moving stream of water, and events in time are rocks that guide its path. If you go back too far and move a rock, the stream won’t line up with the rest ahead of it and those events don’t happen. And you can see it in what she doesn’t do. Despite the threat Eris poses in those futures, a somewhat corrupted Eris was needed to win. She had to suffer on the moon, to be put on the edge of corruption, to learn what she needed to help us. We had to be there to reel her back and keep her stable. So Elsie couldn’t interfere, even though her loop goes far back enough to intervene. She had to keep that major risk in play. Some stones can be moved, some can’t. If you have any questions lemme know.
