Does the specific nature of your post mean that you are actively not interested in Hunter: The Vigil?
That splat is currently the focus of the game I am running, which is at a point where new players could be added in relatively easily, as direct supernatural elements are to shortly be introduced.
I plan for mystery to be important, though not necessarily central, to the game, and it will not be restricted to Hunter-type characters. All supernatural templates except for Mage are possible; magic will be handled with different rules.
If you are interested, and note that I am not always the quickest poster, depending on how much work I have at any given time, here is a link:

Note that the game is rated Adult, because pulling punches isn't my thing.
Finally, you do not have to begin as pure mortals, since your character(s) will, in all likelihood, be joining in Chapter 3. If you do want to start with a supernatural template, we'll work out what kind of powers you have.
Thank you for reading.
