Soteria "Tory" Kafieri is the granddaughter to Theo, a survivor from WWI who was saved by Acheron Parthenopaeus, her husband. She's an archaeologist who was trying to prove the existence of Atlantis like the rest of her family before her. Acheron, while in disguise, embarrassed her while she was giving a lecture about a journal she had found at a dig site that she believed was Atlantis. This journal lead her to Dr. Julian Alexander, who was the leading expert on Ancient Greece. He told her he couldn't read the journal but thought that he might know someone who could.
