My theroy,
while re-reading the TWMF I noticed a somthing said by Shehyn "Once there was a great realm peopled by great people. They were not Ademre. They were what Ademre was before we became ourselves.
"But at this time they were themselves, the women and men fair and strong. They sang songs of power and fought as well as Ademre do."
this tells us two things Songs Have power like names, thus why Kvothe's family was all killed off.
Second this also says that Kvothe will have to learn how to sing with power and and fight to kill the chandrian / Cinder-
tell me what you think!
