Game of Thrones: The Impaler.

"Oops, You Died—Now You’re a Vampire Lord in Westeros!" Unfortunately, your life has come to an untimely end—and to make things worse, you can’t remember anything. But death isn’t the end for you. Instead, you’re given a second chance: rebirth in the brutal world of Westeros… as a Progenitor Vampire, one of the most powerful of your kind. As a welcome gift, you’re granted a few special items to help you survive. But there’s a catch—you must complete dangerous missions in this unforgiving land. From navigating the Game of Thrones to facing the horrors beyond the Wall, your new existence won’t be easy. —good luck, you’ll need it! I'm delighted to have reached so many people. If you want to continue supporting me, I'll leave my Patreon where in a few days you'll be able to read all the chapters (so far) of the story. pa treon.com/TheJagger — Description from novelcodex.org
