Salvatore but also a Mikaelson? (Niklaus's Daughter)

Hi everyone I'm Rosaleen Salvatore. Well actually I'm not really a Salvatore I'm adapted. My family abandoned me when I was just a baby. The Salvatore family always raised me. My baby brothers Damon and Stefan don't know, nor will they ever. Damon and Stefan are regular ordinary vampires but me I'm a different type of monster. I have some werewolf, some witch, and some vampire in me. Whoever my parents were, they were powerful. I stopped aging at the of age of 17, my 'father' noticed and decided to kill me but what he didn't know is that vampire blood was always in my system. They had a funeral for me and Damon and Stefan were heart broken to find out their older sister died. Now I'm on my way to Mystic Falls, where I tracked them down, to surprise them.

But what Rosaleen didn't know is that she was going to be meeting her father and real family. She also can't be compelled by Originals.

Niklaus is a tiny bit nicer then usual. Rebekah is the same. Elijah is his usual gentlemanly self. Finn doesn't want to die. Kol is a big softy but has a dangerous side as well. Freya is a immortal witch. Don't underestimate the Mikaelson family, they will kill anyone and everyone if they hurt their little Flower.
