"So you told them I can use charm magic?" Arin asked me when I told her about what I told the Vampire King and his wife this morning.
"Yes. Because it's highly likely that there's an entire faction of vampires who are related to the cult. And the leader is most likely a Vampire Duke. I told them that maybe you can use charm magic to charm that Vampire Duke and make him answer everything honestly," I said.
Centaurs can tell when someone is telling lies or truth. But they can't make them talk honestly unless they torture them first. Though there's a chance that the one that they tortured won't talk at all.
That's where Arin came. If she's willing to use her charm magic, then it will be easy for her to make any male to speak the truth. Her only weakness is that it doesn't affect female. But since the one we're targeting right now is a male vampire, I think it will be fine.
