User blog:Valerio Mariani/The ages of "The Quartet"

I've always been curious to know how old are the members of "The Quartet" (id est Merlin, Arthur, Morgana and Gwen). I read many posts and comments on the wiki, but I want to show you my calculation.

From the oldest to the youngest:

Morgana  should be the oldest of the four, because Katie McGrath confirmed in an interview that Morgana is the oldest of "The Quartet". I assumed she is little less than 2 years younger than him. She should be  22-23  in Series 1 and  30  when she dies!

Gwen  is younger than Morgana and I think she is slightly older than Arthur, I think she is 21-22  in Series 1. So she is  29  when she is crowned queen of Camelot.

Arthur should be younger than Morgana. His actual age is easy to calculate, because the Great Purge ended 20 years before Series 1, meaning that he is around 21 in Series 1. There has been eight years between Series 1 and Series 5, so at the start of Series 5 Arthur would have been 29. Assuming that 1 year has passed between Arthur's bane and the diamond of the day, Arthur is 28 when he dies!

Merlin the youngest. He is 17-18 in Series 1, because the introduction had him as a young man only in Series 4 and Series 5. He is 25 at the end of the show.
