The Valemont Professor that helped Sophie Fields a.k.a. Maggie Gracen become adjusted at Valemont University.
-SPOILERS ALERT- Edit
The Professor had always been very invested in each of his students, but he took a special interest in Sophie/Maggie due to her and her brother likely being from the Desmodus vampire bloodline, which is the most powerful bloodline. Sophie/Maggie wasn't sure at first if his interest was for a darker purpose, but he proved to be crucial to her survival at Valemont University.
It was revealed that the professor was not a vampire himself, but rather married a vampire, who's an architect in the city.
Professor: "He works as an architect in the city."
Maggie: *looks at picture* "But he's-"
Professor: "-incredibly handsome, I know."
Maggie: "Don't get me wrong. I don't have a problem. I'm just a little surprised."
Professor: "What? That I'm not a vampire? Or that I'm gay?"
Maggie: *hesitates* "...All of it." :)
