An evil entity that eats your children.
Oftentimes, it will go up to the roof of the house across the street, and just stand there, watching you...
If you try to kill it, it will regenerate and call more kelet to the roof of the house across the street. They will stare at you through the window with those evil eyes and that satanic smile... After a while, they will tear your door down and drag you into the infinite darkness... Not even blast doors can stop these purely evil creatures...
