The Great Geek Manual

There’s power in the night. There’s terror in the darkness. Despite all our accumulated history, learning, and experience, we remember. We remember times when we were too small to reach the light switch on the wall, and when the darkness itself was enough to makes us cry out in fear.

Get a good ways out from civilization-say, miles and miles away on a lightless lake-and the darkness is there, waiting. Twilight means more than just time to call the children in from playing outside. Fading light means more than just the end of another day. Night is when terrible things emerge from their sleep and seek soft flesh and hot blood. Night is when unseen beings with no regard for what our people have built and no place in what we have deemed the natural order look in at our world from outside, and think dark and alien thoughts.

And sometimes, just sometimes, they do things.
