Corvane is the last true blood of a northern kingdom the dark took generations ago. The kingdom is gone. The claim is not. He grew up knowing a birthright that buys nothing, in a land that has forgotten it ever had a king.
The line in the north
He does not sit a throne; he holds a line. As a ranger of the Failing Marches he keeps the failing north against the rising cold, the last discipline of a heroic age that no longer pays for heroism. Every season the blight climbs a little higher, and every season he holds it a little lower down.
The crown no one remembers
His wound is not loss but irrelevance. The age has no use for kings, and a rightful heir to ashes is a joke the world has stopped bothering to tell. To claim the crown is to be laughed at. To abandon it is to let the last of something true finally go out. He has spent his life refusing to do either.
What the age asks of him
The turning of the age will put a choice in front of Corvane that no ranger's discipline answers. Whether he can be more than the last defender of a lost cause, whether ash can be built on, is a question the saga does not answer lightly, because the honest answer might be no.
