Dragon age: Rebirth.
Prologue:
It was fearsome and near impossible task but the last remaining two Grey Wardens defeated the blight and win the civil war, and managed to keep both of their lives,thanks to blood magic. An art which is strictly forbidden and if caught practicing, they would be shown no mercy. But this story isn't about what they did, or how they became such heroes. This is the tale of the person who made them the heroes.
