So, in Oathbringer, Jasnah is communicating with those two informants, one of which promises information about Truthwatcher spren. One of the informants (the one who starts with a p) says that he thought his news of a sighting of Axies the Collector was interesting. This implies that Axies is not only slightly famous but is also of some note to Jasnah, who is researching the Voidbringers and Knights Radiant. I don't really have any theories about this, but I was wondering if anyone else did.
This forum is just for any theories about Axies or his research.
