Reading over the system now. Hmm. Modern setting, underworld Miami, occult underground. Oooooo. Magic may, and I stress may exist in the more shadowy corners of reality.
Hmmm. How about a Street Doctor? Knows a lot of people, has a lot of connections of questionable reliability. A competent source of medical care, rather unusual for the type, she is not herself an alcoholic or drug addict. So she has some goodwill from very dangerous people, has been a middleman for contact between factions. And you know what can happen to people in the middle.
Former US Army Medic medically discharged because in the Western desert of Iraq, in the ruins of a city, ruins so old they were nothing more than a raised spot in the desert really, so old nobody knew the name... she saw things, she heard things. Maybe hallucinations, maybe real. But regardless of what the shrinks told her, and a natural suspicion of the dramatic license of ghost and monster hunter shows.... she's not ready to dismiss accounts of something weird going on.
Whether she's right to think so or not, we'll see in play. And besides, even if people who are motivated by that stuff might be wrong about what they believe, they can still be dangerous.
