Backstory you are (pick what creature u are)  and you met Carlisle in 1980 cuz he turned you since you were dying on the side of the road (you pick what happened). Anyways you have an incredible bond with your step siblings which are Edward Cullen, Jasper Hale, Emmett Cullen, Alice Cullen, Rosalie Hale, and your step parents Esme Cullen and Carlisle Cullen. You go to school which is boring since you have been going to school a lot but that's besides the point. You or your brother Edward has fallen in love with a human named Bella Swan. So she knows about you and ur family being Vampires.

BUT here's the thing in order to keep her safe you and your entire family packed up and left and that led to Bella being depressed and stuff. So Bella tried cliff diving and that didn't end well cuz Victoria a vampire who was getting revenge for her bf who got killed by the Cullens was going to kill Bella for revenge but that didn't happen because Jacob saved Bella.

Anyways fast forward Alice gets a vision of Bella dying and you go with her to check while this is happening Edward went to the Volturi to get himself killed. But that didn't happen cuz Bella got there just in time before Edward could expose himself to the humans.

Fast forward again you, Alice, Edward and Bella are in front of the Volturi. You and Alice are standing your guard just in case anything happens along with Edward. But that's when someone speaks up.

You Vicious little b!tch!!.. Caius says as he is sitting on his throne.

While everyone is stunned at what is happening all looking between you and Caius.

Say it again sounded good you say as you look at him dead in the eyes as his lips form a smirk.
