Professor Penthesilia took the name of the famous vampyre Amazon queen Penthesilia when she was Marked in the early 1920s. She prefers that students call her Professor P. and the written word is her first love. She teaches subjects ranging from classic literature to current bestsellers and popular fiction. She enjoys reading, hiking, and collects vintage jewelry. She has many memories of the Titanic, because, like Neferet, she was living in Chicago at that time.
