In the underground cellar, Carl was making a few last touch-ups to his preparations. Charlotte was still tied up to a chair with the magic circle beneath her, and then there were the two other so-called volunteers that were placed in their own magic circles as well.
He carried several large glass jars and placed them just behind where Charlotte was sitting.
"This bit will hurt slightly," Carl said with a smile as a needle was placed into the top of Charlotte's hand and then some sticky substance on top of it. Oddly, the flow of blood didn't come down the tube that was currently inserted into Charlotte and into the containers.
The same was then done with her other hand. Not too far off to the side, Charlotte had also noticed other containers with strong glowing magical energy.
