There's a related question which asks whether a map exists that shows where the various humanoid societies are located. That's fine, but is there a map of the galaxy that shows all canon civilizations/beings, and not merely humanoid ones/common ones?
My original question was going to ask where Metron space is, and how close it is to Organia. But then I wondered about Nagilum, and if its void is close to Metron space, or Organia, or the Edo god, etc. Now I realize that Nagilum is located in the Morgana Quadrant, but that doesn't say much.
Also, there are a lot of powerful physical beings from TOS, such as the Providers ("The Gamesters of Triskelion"), Flint, Apollo, etc. I don't know that the aforementioned map has the planets of these beings labeled. I'm inclined to say that it doesn't.
