Talia's special advisor
"Introduce me as your special advisor", Cornelia demanded from Talia. "Considering the mystery surrounding the Midnight Guardians pack, no one will dare to question it."
Talia didn't see a problem with introducing Cornelia as an advisor, or as anything else Cornelia wanted. After all, other than Yasmin, Cornelia was the second witch that provided assistance without demanding some kind of a deal for the smallest things. In addition to that, Cornelia was mated to James, a teenage genius, and doing a favor to Cornelia will definitely help them keep James as their ally.
However, Talia was concerned about Cornelia's safety. If Cornelia gets compromised and people realize her special background, Cornelia will get a big invisible target on her back. It will also cause a cascading effect where everyone close to Cornelia will be put under scrutiny. Talia already had so many problems on her hands that she didn't want to add more.
