One of the ideas I've had for years is a massive monolith cut out of a deep black stone covered in irregular etchings. It is cut in a roughly square shape, with an angled topside. Although it's in a verdant and lush forest, there is a 5 yard clearing around it where absolutely no plant life is found, and there is no wildlife in a large area around it. Standing next to it one can feel a slight chill, even during an otherwise warm and sunny day. On one side, the etchings give way to the image of a massive door, cut in the same style as the etchings, but more regular.
I plan on giving no hints as to what the monolith is, its purpose, or its age. I think that a little mystery in games can only be a good thing.
