Monsters origin?

[Maggie]

I was under the impression that they were creatures Alexander made to go out and kidnap people for him.

One of my favorite things about the game, though, is that it leaves a lot of things sort of a mystery. It doesn't feel the need to explain everything away or risk taking away any of the fear. What they did to help give you an idea of the nature of your enemies (which they also used to great effect in Penumbra) is fantastic: finding notes or books relating to folklore, rumors or local legends. That's a fantastic touch and I love how it skirts the line of coming right out and telling you what's going on. The fact that you have this level of connection to the world by hearing about other peoples' experiences or perceptions of the creatures just draws you in even further.

I wish more horror games/stories would use this, because it's a good trick. The only other example I can think of off the top of my head is from a movie called Fire in the Sky. It's about an alien abduction that occurs in the woods, and at one point, a TV reporter mentions that this particular area has a reputation among the Native Americans who claim it's a bad place where demons come from the sky and kidnap children.

It's one small throwaway line, but it gives the story a depth that it wouldn't have otherwise.
