Larentia, a giant but gentle griffon formerly of the Frozen North, has settled comfortably into a life of crime fighting and royal palace guarding. Once member of a rare tribe of griffons, Larentia has done everything in her power to put the past behind her and move on.

But when a cold wind passes over Equestria, Larentia finds that her past may not have been so left behind as she had hoped. Now that it has caught up to her, it is up to her and her best friend, a rough and tough dragon named Dagmar, to stop it from turning Equestria into a frozen wasteland.
