Mark slowly walks to the open door, hoping to catch the invader in the process. He readies his cellphone, prepping to call emergency if the prowler is still about. As he comes up to the doorway, he sees nothing's been moved. He notices a strange electric charge in the air, and all the hair on his arm begins to stand on edge. He rounds the corner to his living room, when he notices a strange glow. In the corner, sitting in his favorite chair, is an entity like he's never seen before.
"W-who are you? W-what are..." Before he could finish the next sentence, the being rushes him, knocking him down to the ground. The creature sits on his chest, pinning him to the floor.
Hush, mortal. You know not who I am, or why I am here. Trust that I will not harm you, and I will let you rise. The entity speaks to him telepathically, or at least that's what Mark is at liberty to assume. He shifts uneasily under the creature, noticing that it's weight is virtually nothing, yet holds him firmly.
