The Bloody Wolf of the North

What if Jon had inherited more than just Lyanna's colouring. What if he, like his mother and his uncle Brandon had the 'Wolf's Blood'. A what if story featuring Jon as a rather more assertive character than he is in the books or show. Standard warnings for GoT/ASoIaF fics. Violence, blood, sex and gore. Butterfly effect. Things will be different and the same. Mix of GoT/ASoIaF.
