Wheel of Time - TV Show on Amazon Prime

but I think it is an accurate reprsentation of what a massive mountain at 8 o’clock would look like

I guess this is where we have to agree to disagree. To me there is no way that mountain is below 9 o'clock. I can't see how to argue this further without a 3d model, and I don't have the graphic chops for that.

I thought it was stilled called “The Caemlyn Road”, but now I’m second-guessing myself on that.

Interesting that the name "Caemlyn Road" only appears in TEotW with respect to the east-west thoroughfare of Andor. It is never mentioned again.

My reasoning however is that the Road directly connecting Caemlyn and Tar Valon is a massive thoroughfare, and despite there being about 100 people or so on it, the tiny 1-foot-wide dirt path we see around the 7:01 mark in S1E5 is absolutely not that.

Agreed, and I noted earlier that I could buy that the people on the road were refugees from Cairhien.

Look at your map, though. I swear (but can’t cite) there were formally a few small connecting roads between the road from Caemlyn and the Cairhien Road (the latter is correctly named).

I'm having trouble finding a reference, but I'm fairly certain that there is no crossing of the Erinin between Aringill and Tar Valon. (The wonder girls mention there being no crossings of the Alguena with the maidens in TDR, but oddly they don't actually mention how they got across the Erinin) They might have been able to catch a barge or swim across, but why? Without some explanation for that, it is natural for anyone watching (and looking at Amazon's own supplements) that Mat and Rand approached TV from the west - regardless of the director's intent.
