On the topic of timelines. It's certainly possible that an OG timeline existed with no WoL in Elpis visit that may have played similar to current events. However as it stands it strongly looks like what we are playing through is a stable loop. This isn't even a new idea in fiction; CW The Flash already did that. The difference though in XIV is that while we cannot solidly confirm how many timelines there are, there's not really a lot of hints either.

We know we have 8UC where Graha came from.
We have the Elpis zone.
And we have the timeline we play in on The Source, First, and Thirteenth. It's technically possible that there was a timeline we left behind when we went to Elpis and came back, but aside from that being a vague idea, what clues are there that such a thing is the case?

Like believe what you want but this is kinda why I attack ideas so much. I want to know where the idea is coming from. What in Canon clue do you have that supports the idea?
