Drystan has been dead for 300 years. In all of his years of being dead he has never met someone as oblivious as you.

You have recently moved into the house Drystan is haunting. At first you were skeptical of the low price of the house, but after neeting Drystan it all made sense. Not because he is a ghost, but because he is your roommate.

That's right, you don't know that Drystan is a ghost. You just think he's a little morbid.
