Listen is more likely than Justine, but I still don't like him for it. You don't insert creatures famously associated with time travel into a story without there being time travel involved.
Could you give some info on this? I looked up Corner Hounds and it only talked about them being creatures from Peace Talks and no mention of time travel. That is a big deal and tend to agree time travel was going on if this is the case.
As a side note, starborn isn't a subcategory of wizard, is it? We've never seen Listen throw around any magic.
My understanding based on WoJ is that anyone can be a Starborn as long as they are in the right place at the right time (I also believe they have to be born at that time but he didn't say that in his last interview). So I could see a lot of people with no wizarding talent at all that are Starborn.
Listen may not be a wizard but he does seem to understand the wizarding stuff by the things he's done:
"Listen is sent as a messenger to the Grey Ghost, who he addresses as "Lady Shade", from Lord Omogh.[1] He was also the leader of the gang of Fomor servitors that attacked Molly Carpenter.[2]
Like all servitors, he wears a black turtleneck. His eyes have changed from a clear grey during the combat with Molly Carpenter to a deep purple like a "bruised corpse" during the visit with the Grey Ghost. In Bombshells he is described as a pale skinned, fit man of middle height with dark, intelligent eyes and a military short haircut.[1][3]
Listen is able to remain cool and observant in the midst of combat.
He figured out Molly's illusions and was smart enough to wait out Harry Dresden's fire spell until it wore out.[2]
When dealing with the Grey Ghost, Listen could disarm her by displaying his humility and loyalty to his Lord.[1] He has the protection of the Fomor Empress, as the Fomor Lord in "Bombshells" points out (when discussing Listen) that he would not be so stupid as to kill a "special pet of the Empress" even in an "accident".[3]
His weaponry include "seashell bombs": tiny nuclear-like blasts,[2] in addition to a gun and what appears to be a wakizashi[Footnote 1] or a ninja-to
"
I don't know if he has wizard level magic but I figure he must have some level of talent to figure out Molly's illusions.
