MitD XIX: The Potted Plant Is Starting To Look Reasonable

[Keltest]

In an effort to avoid reliving an argument, I'd like to point out that the first three points are the theory, and the second three points are an example that fits the theory. You can reject the example if you wish, but I think the theory applies even to a modest Monster in the Dark whose importance to the plot isn't mission critical.

If you want to die on that hill for whatever reason, its still not useful criteria because at this point, ANYTHING can be behind the darkness. It already has a reason to be in the plot, a reason to be behind the shadows, and the third one is honestly just a rehash of the first one.
