   Summary

   After the Second Wizarding War, Harry Potter leaves Britain behind and becomes an adventurer. Ten years later, he returns to Hogwarts, only to battle a Hebridean Black that tears open an ancient road between worlds. Harry falls into Westeros with a thestral beneath him and a dragon at his back. Mistaken for a dragonlord of Old Valyria, Harry finds himself in the North, under the wary protection of Eddard Stark.
   As Haerys Peverell, the Last Dragonknight, he will not only change Jon Snow’s fate — he may change the fate of Westeros itself.
