There's an actual reason why each Daughter of Qye had to spend the rest of their life inside Suttern and protect the Kingdom.
And it's not only because Qye needs protection.
Or because Qye didn't want to be involved in a war.

Werewolves are widely known as the enemy of most creatures, there was never any good history between Werewolf and other creatures.
It's been almost a thousand years since the war that had claimed Tioddre Castle, the one where since then Suttern has changed its name into Suttern Castle.
A long time ago, a Royal Hybrid by the name of Wylard has stated he will not continue the legacy of his empire and anyone who wishes to claim the land and castle should come forward.
