> where and when do the shades come into the picture?
Nod Krai is a filler region. The shades won't get involved until Snezhnaya.
The lore drop video was just thrown as a consolation after Natlan obliterated any remaining hype the game had.
On a positive note, their stated goal for Nod Krai is to tie loose story ends for other regions. That's actually good for the game and arguably the best possible thing they could have done.
