marauders4evr:This is one of the first things that I thought of when I saw that Book 4 of LOK would be set three years later.If you were twelve when ATLA first came out, then nine year later, you’re going to be twenty-one when LOK ends. Which means that you were the same age as Aang when ATLA started and the same age as Korra when LOK finished.And I don’t believe that this is a coincidence at all.It’s standard in children’s entertainment to put the protagonist’s age (explicit or assumed) between 0-2 years ahead of the ‘ideal’ target audience’s.Presumably the writing crew were very interested in holding onto the original fanbase. -- source link
