Other than the drinking of blood, the consumption of flesh, prayer, flagellation, and insense/candles of various kinds, would those with creative minds or broad knowledge be interested in coming up with some ideas for how the Ecclesiarchy and the various minor cults would practice their religion? The ones I know of are various forms of "mutilation" (its a controversial word, as some include male circumcision in the mutilation catagory), baptism, annointing, and ritual scapegoating... I'll add more when I come back in a bit, or expand on some ideas.
