What is up with Wit in the very last page of OB? Wit tells the spren that he is “certain the reason he came to [Kholinar]” was to find the spren. This is odd for a few reasons.
First, It is not really at Hoid level importance - The end of the last two books were important events that Hoid had to witness/be a part of. The first being Taln returning, proving to both the reader and people in world that Dalinar was right, and the final desolation was imminent. The Second was proving to the reader that Jasnah Kholin was alive, and important in world because Hoid had to put the future Queen (Or maybe still referred to as King) of Alethkar towards the tower and give her sketches of the Heralds, as well as bring her up to speed on current events. Obviously, this spren is important, because out of an entire Cosmere of places to be, Hoid goes to save it.
Secondly, It seems like the Fused also know it is important. The Fused would not tell Moash why they were breaking apart the temple, but the wall that the spren was hiding in “was one of the few remaining”, so it can be assumed that the fused were literally tearing the city apart to search for it. The Fused in charge of the destruction of the temple has met Hoid before, and we are told that Odium would be willing to destroy the city in the off chance that he may kill Hoid. This means that saving the Spren put tens if not hundreds of thousands of people at risk, which is not something Hoid does lightly. I know he said he would watch the world burn to see his ends met, but he does seem like he would do it lightly, especially after putting time, energy, and investiture into saving just one little girl.
Also, this may seem obvious, but the spren seems to be a cryptic, as it is described as “a pattern” and Hoid tells the spren that he knows many juicy truths.
This can only mean that this cryptic is of vital importance, and cannot be dismissed out of hand. Does anybody have any clue as to why?
