Who is the daughter of Thena?

Could you please clarify who you are referring to when you say "Thena"? Is she a character from a specific work of fiction, such as a comic book or a movie? If so, could you provide more context about the story or universe in which she exists? Without that information, it's difficult to accurately answer the question "Who is the daughter of Thena?" as it's not a commonly known or universally recognized fact. However, if Thena is indeed a character with a known family history in a particular story or universe, I would be happy to help you phrase the question in a more appropriate and informative manner.
