“Mortal energy is an interesting thing.”Dark hummed, and wistfully drew his hand across the air, mimicking a smooth silhouette of a human body.
“Imagine a magnetic aura of space surrounding your body, like a force-field, puppeteering you along throughout the mediocrity of your life. It is a precious and powerful thing, individualized and so very important to keep you safe, and sane.”
His smile grew as he continued, seemingly pleasured by the ability to describe just how he would leech himself into their being.
“When you let me in, you allow me into that delicious, vulnerable piece of yourself. You allow me to pick off of that energy. To manipulate it at my will. To keep track of it, and harbor it. You give it to me for my disposal, but at the same time, you give it to me to look over, and care for, and protect. You give it to me to fill the emptiness that would otherwise be there. You allow my own energy to co-exist with yours.”
His arm fell gracefully into his lap, drawing his head to the side in order to finally lock eyes with them.
“It is a tragic romantic story of ownership, and freedom. Give and take. When you let me have you, I have you entirely. Your body, and the energy that keeps you. That is what letting me in means.”
