The Grimataur is a creature of the night that chooses who can see it. It finds a victim who it will then follow and begin to slowly destroy that persons life to loosen the soul from their body, as a person with no will to live is the easiest to have their soul ripped from them. By selectivly making itself visable to its prey it slowly drives them into madness and paranioa, bringing all their friends and family to ignore and shun them.

It is at this point the the Grimataur makes it's final strike.
