In Game of Thrones we see the Red Woman Melisandre remove a necklace which presumably acts as a glamour and gives her the appearance of a young woman. When she removes it we see that she is in fact rather old and decrepit. Considering her god is known to bring people back to life, particularly those he still has a use for, it is not unreasonable to imagine that she has extended life in order to fulfill her Lords' wishes. So just how old is she? I'd prefer answers to focus on TV show canon, but in lieu of that references to the book work.
Not a duplicate of What is the explanation for Melisandre (Red Woman) seeing her reflection as old and frail? for two reasons:
- That question is completely different and the answer only tangentially happens to pertain to my question. If, however, I accepted the response of the actress as a valid source then I would probably support the duplicate anyway because, hey, I got my answer, right? Which of course leads to:
- The actress, as noted in this answer, states she does not know how old the character is, has not read the books, and is merely speculating.
In my opinion that leaves this question still canonically unanswered.
