It's a love potion

It's a love potion. Tuned to me thanks to a drop of blood. She'll fall head over heels in love with me the second she sees me. I'll have to work on her a little to wear her down. If I ask her to enslave her sisters the minute I meet her then her mind will snap. The fact she feels she loves me will conflict with the fact she knows that is wrong. I have to convince her what I do it right."
