"We are all searching for someone whose demons play well with ours" - Sierra Gilbert.

When the people we love die we became upset, angry, frustrated, and emotional. We are unable to show our emotions in front of people not because we care about what they say nor think it’s because no one will ever understand. No one will ever understand loosing someone you thought you potentially loved until that person is no longer alive and you then realise all along that this person had captured your heart and ripped it out once they left. Niklaus Mikaelson never thought he would be grieving about the death of a pathetic human, but Sierra Gilbert isn’t any pathetic human. She was Niklaus Mikaelson’s love. A man like Niklaus does not grieve like a normal human. He grieves like the monster he truly is. He grieves by killing people and shedding blood. Every country, every little city Klaus has travelled to find a resurrection spell to bring back Sierra but somehow each spell fails. It’s been months; nearly a year since Sierras death and one thing for sure is that Sierra Gilberts death has affected everyone. From what we have been told, apparently the afterlife is happiness. But is it really? Is being trapped in a cold cave, with hungry wolves and a stranger who will never answer questions happiness? Its only one thing that Sierra wants as she gets her memories back and that is to be resurrected and take her revenge on her lovers brother. But that isn’t as easy as she thinks. It’s not the spells or the witches that bring back Sierra. It’s up to Sierra to bring herself back from the dead by finding her own strength within her, by finding out her true potential and by finding out what she can really do to the man that put her in this pitch, black, cold hell hole. “It wasn’t the power of love that brought me back, it was the deep burning desire within me, that brought me back for the bloodlust and revenge.”
