In which ASoIaF stops pretending to be a low fantasy setting when all the magic comes back, thanks to a misplaced demonically corrupted Silver dragon. Good does not always triumph over Evil. What has been lost can not always be reclaimed. What has been forgotten cannot always be remembered. Some decay is irreversible. Winter is coming, but it will not do so alone. If the world doesn't end in fire, salt or shadow first?
It will end in ice.
It will end in ice.
