Races: human, harrowed or something from Accursed with GM approval, all use dominion from harrowed.
Occupations: A player can make any kind of character from a professional dancer to a guide. Here are some examples:
Ex-soldier (deserter or honorably discharge)
Grifter (con artist)
some backgrounds might come into conflict. The blessed and Templars don’t play well with others viewing chi users, shamans, and practitioners of voodoo with suspicion and the tainted with horror. Most citizens in Deadlands will view the tainted with disgust and will plot against them if their powers are known (or in the case of automatons if they realize they are acting on free will) but especially the blessed.
neutral but distrusted:
Some weird scientist graft human an animal parts on people. They are called Rippers. Rippertech is implanted with a successful healing roll by someone with the arcane background weird science.
