Lion Knight of the Northern Sky{Rewrite}

Eddard Stark, Lord of Winterfell and Warden of the North had just executed a deserter of the Nightseatch, accompanied by his sons Robb and Brandon Stark, and his bastard son Jon Snow. On the way back, they recover six dire wolf pups after their mother died killing a stag. They then find a knight bearing the sigil of a lion lying in the river, suffering from hypothermia, nearly drowned, and body broken. They bring him back to Winterfell and tend to him while he lies in a coma over the next few weeks. King Robert Baratheon then arrives and offers his best friend Eddard Stark to be the Hand of the King following the death of their father figure Jon Arryn, who served as the previous Hand. How will this new player in the Game of Thrones turn the tide.
