Spoilers for spaceage Cosmere

Gooood golly. So, I just finished RoW, and listened to the SoD sequel reading. Jesus christ there was a lot there.

So it looks like there's growing evidence for a future Scadrial and Roshar conflict. Ornamental masks and metal launchpads for the ones above, and a space-age knight radiant with a shardgun good golly.

With what we know following RoW, do we believe this is a culmination of the Rosharan triumvirate coopatition and Odiums ambition? And who leads the Scadrial conflict? From the masks mentioned, there appears to be some mixing of the continents and traditions. Kelsiers continued shenanigans?
