I like it. An original idea (at least for me), using Faust as the cornerstone of magical division. And I do enjoy the idea of something like this without necessarily the incredibly dark Lovecraftian overtones. This reminds me of Supernatural, and that's a good thing I think!
Very original concept. These things existed, but they don't anymore because some guy did some Epic stuff and sealed them away, only he then trusted someone who turned and tried to undo his work for love. Nice. Never explains what happened to Able either, and I like that dangling hook.
Very inspiring also. You could be anyone, and you could be into anything. All you need is the intentions to stop something evil or figure out what is causing all the weird happenings, etc. The fact that it is occurring in the here and now does limit the options a little, but not significantly. And the chance for humor in character gen is high (last gay man cut from the Queer Eye foursome before they went to filming teams up with Daisy Lou, the southern belle from Danger, Arkansas... etc.)
Very good presentation of the concept.
