Something doesn't add up regarding the connection between Amdapor and Norvrandt...

It's actually a bit complicated...

To traverse space and time, the Bad Future Ironworks had to retrofit the Crystal Tower with tech gleaned from Alexander (Time) and Omega (Space). You could just use Time, but that wouldn't let you cross over into the First where the Calamity was rooted; with just Space, it would already be too late to stop the rejoining. In order to truly move through spacetime, you'd need both the wings of time and the power to traverse the rift.

I... doubt Amdapor had those powers, but even if that's the case... there might be some other explanation we just don't know about yet.

To successfully navigate it and travel to another shard, you're absolutely right (and I'm aware of how they pulled it off, since they explain it in the Twinning)...but that wasn't what I was suggesting, at least as it relates to the Amdapori.

I was suggesting two things. The first was that the way the rift works allows for one to look at multiple points in time, so that if one were to understand how to traverse it and could produce the power needed to accomplish it, they could go forward 100 years, then back 45, then forward 500, then back 1000 (obviously doing it that much would likely have disastrous effects on the timeline if you weren't an invisible observer of some kind)...as the rift itself exists outside of times flow. It would all depend on navigating through it to the point in that sea of chaos that gets you to the when and where you want.

The second thing, and I probably should have been clearer on this looking back at my post above, is that when the Amdapori managed to see what they did...it was not necessarily their intent to seek to navigate the rift, and that their glimpse at seeing this creature from another plane of existence was a chance event...and that it's the chaotic nature of the rift, existing outside of time as it does, that allowed for this society over 1500 years prior to see creatures (and I do think they only saw them, rather than going to where they were or having one make it on to the source) that we would then see in our time, on a world where only 100 years had passed between their creation and our arrival and subsequent defeating of them.
