The Devil In Me - Elijah Mikaelson -

What if Hayley gave her search for a cure for the Mikaelson family up?
Would someone else fight harder to save them?
Maybe this person hasn't shown up in the spotlight yet.

Amelia is the ghost lurking in the shadows of the Mikaelsons. None of them saw her face yet. Ancient history and desires of revenge made its way into the vampire and a hatred with the force of a wild storm developed. She wants nothing more than seeing the Original family dead. But for one of them she wishes even more. Elijah Mikaelson would suffer, when her plans are fulfilled.
But Amelia is just the lackey of a much bigger threat facing the Originals.
