There is a character who has to be a venin after Onyx Stormrevealed the perfect counter signet to their power, which would set up a major new conflict for the series. While there have been many Onyx Storm venin theories that have cropped up ever since the book's publication, few really dig into how deep within Navarre the venin have gotten to, even now that Navarre is no longer ignoring the threat. The focus, rather, has been on other aspects of the venin, which makes sense considering who is currently or who could be turned.
