Reborn as a Direwolf from the Start: How Do I Survive in Game of Thrones?

A Game of Thrones fanfic, a legend of the Direwolves of the North.

Others start out as powerful big shots, but I start out as a big dog. Others start out blessed with divine strength, but I start out fighting for survival in the wilderness. Tell me, how is a Direwolf like me supposed to survive in the world of ice and fire? The Game of Thrones is for people, but I'm just an utterly ordinary little puppy!

[Reader advisory: A self-indulgent fanfic, a Game of Thrones prequel. Rhaegar is the male lead. The writing is rough and the logic is questionable, so proceed with caution. This is set half a century before the events of Game of Thrones, when Westeros's schemers and victims had yet to gather, and tells of their childhoods.]
