Notice(For some changes in chapter 4 and beyond)

I changed a few things to make it clear that in all ways that matter everyone here is 18 or older. Other sites seem to hate that I explicitly stated our hero's age(less than 18) in chapter four. So I am changing that and combed through the other chapters to see if it is stated anywhere else. I changed it where I could and am going to use the metric going forward but if anyone finds any legacy mentioning, please point it out so I can change it.
