Harry Potter and Game of Thrones Challenge
There are several stories of Harry being reborn as a Targaryen, Baratheon, and Lannister.
This however is a challenge to any who want to make him a Tully.
Rules for the challenge
He must be born after Lysa but before Edmure whether he is solo or twin is your choice.
He also must improve the defenses of the Riverlands to make the Westerland invasion easier on the Riverlands
Finally he must get a Valyrian Steel sword how is up to you as is the name but my suggestion is Red River.
