Gray Tides

Full Title: "Black Skies, White Lies, Gray Tides"

Legend goes...

A chosen one of the dragons will either become the hero of bright, destined to save the land, or become the villain of dark, destined to destroy the land.

Since the dragon shift is actually a set of twins, something that has never happened... at least not recorded, the choice of either being the hero or the villain is null and void. Corwin is destined to be the hero and Cora is destined to being the villain. However even those from the light have dark in their hearts. Who is to say that destiny is set in stone?
