An Unlikely Love Story

It was an unlikely love story, and even more unlikely to last as long as it did.
It was an impossible love story, and even more impossible that it didn't end for as long as it did.
It was an insane love story, and even more so when you have learned all the details of it.
This love story twined two races, two lands, two worlds, and two hearts in a combination of light and dark, good and evil, right and wrong.
And it all started with a boy who didn't want to become a soldier and a girl who did.
