Creator of The Night Brigade Theory [Wind and Truth Spoilers]

The new spoiler chapters this week had some big lore implications. One line about the Night having 'left' has me curious. Here's the quote from chapter 21 of WaT:

“It has been confusing,” the Sibling said, “to learn of all that has happened while I slept. I knew the Stormfather when he was young. I, formed from the Stone, which was the sibling of Wind and Night. The Night left. Few loved her, or even spoke of her, and it seems Mother replaced her with a being of some of the same essence. A new creature, unconnected to anyone’s perception."

One connection with the word 'Night' that we've seen before in the cosmere is from The Night Bridgade in The Sunlit Man. I wonder if The Night has left Roshar and created The Night Brigrade to try to forcefully take control of a Dawnshard for some purpose? Not much on a connection but just one reference of the Night we've seen in the wider cosmere that could be connected.
