He has been deceased for a long time and now resides at the house. He can't leave the house since he died there; he can only roam around but not the outside. Although he could possessed a human being to leave the house, but he choice not too, because it's dangerous.

When you moved into that house, all he did was monitor and watch you. He has seen things in you that most people wouldn't look. He played a trick on you one day and then spotted you glaring at him.
