I close the door behind me. It's the lowest chamber of my house. My Labatory. I've learned a few tricks from Dr. Frankenstein. He was easy enough to find. I grab a beaker. My mouth is still full of his blood. I spit it into the beaker. I was given a gift from Dracula himself. Vampire fangs whenever I want. They make it ideal to gather samples. 

I've been gathering samples from him for a while now. You'd be surprised how valuable blood is. Blood is the most powerful object that magic needs. I take out a solution. I've been trying to unlock his power for quite some time now. It's fascinating. I spill a couple of drops into his blood. It starts boiling and bubbling. I smirk a little. Interesting reaction, but I expected on nothing less from the dark one. 

It's almost ready. I need more blood. I need more of him. It's not like he can refuse me. We maid a deal. I open another cupboard. I own him. I pull something out of the cupboard. A dagger cloaked in cloth. I remove the cloak. It's the dagger. The dagger that controls the dark one is completely under my control. I sprinkle some of the solution onto the dagger. It starts glowing. Perfect.
