People from the fire kingdom can cast flame shield on other people, but only for a short amount of time. And did I say they had to be the exact same age? No. I said "It's okay if they're A FEW YEARS APART" Like, a 22 year old and a 25 year old could be dating, and that would be okay. But if a girl is 14, and a boy is 1000+ then that's pedophilia.
