My MC's are 23 in the last two books in the series. Making it a full decade from the beginning to end of the series. With all the challenges they went through they grew up alot, and there abilities transformed and changed making them the people they are when there whole world is ripped and shattered right in front of them. They end up so used to winning against evil forces that be, used to being indestructible that they completely forget what its like to be on the loosing end. To not win in the end.
I'm so evil to my characters!!!!
