In my books, my main protagonist will go from 19 years old all the way to 91 years old throughout the in-universe years. Old characters will die out and eventually replaced by new ones. I'm currently having four protagonists on separate time range and their respective most active timeframe in the plot are as follows: The 1st protagonist, 1788-1849, most active at 1805-1815. The 2nd and main protagonist, 1830-1921, most active at 1849-1921. The 3rd protagonist, 1854-1894, most active at 1890-1894. The 4th and last protagonist, 1891-1962, most active at 1921-1962. This made me wonders, what are your guys' preferred character age range? I keep feeling that aside from the first protagonist, all of them are not young enough when their part begins. I tried to squish the last one down to at least less than 30 years old since she's the only female among them.
