How old are: Harper, Rhen and Grey? For some reason i picture Harper as only about 16 and Rhen as in his mid 20's so not too much of an age gap but a 16 year old probably wouldn't fall in love with a 25 year old. I see people talking about a love triangle but for some reason i picture grey as late 30's maybe early 40's, even though it says he looks as young as when he earned a post in the royal guard.
