Most of you probably haven't heard about Nathaniel Sinclair but trust me once you meet him you won't ever forget him.
One of the oldest vampires in the world, only coming 100 or so years short of the infamous Original family. Nathaniel has had more of an affect on what's happen in the past of Niklaus Mikaelson than anyone would even think to give him credit for. Now what happens when this particular vampire shows up in the French Quarter and causes a little trouble. I mean he was the first person Klaus himself turned and let live after the family had killed off the first couple they had created. And there is that tiny little fact that something had happened between Nathaniel and the immortal Hybrid. Oh and there is that little fact that Nathaniel himself is maybe one of the most powerful supernatural creatures to have ever/ is roaming the earth but you'll have to find out why that is by reading the book.
