Divine spell-casters are all either theurgists or favored souls. Favored souls are born with divine magic powers and theurgists gain their magic later in life. Most favored souls are marked by their deity at the moment of conception or while in the womb. A small number of favored souls are infused with divine power as children. A disproportionately high number of favored souls are the children of couplings between mortals and spirits or they are the legacies of such half-spirit/half mortals. Favored souls may be marked at a very young age, but they do not normally gain access to their magic powers until adolescence. Some young favored souls are left to fend for themselves but most are visited by a spirit guide in their early life who explains to them who they are and what they can do. A lucky few favored souls retain their spirit guides their whole lives. A lot of favored souls are conceived during their deity's holiday celebrations. Favored souls are usually far more likely to be born to the most devout worshipers of their deity than to those who are indifferent or disdainful of the deity though exceptions, occur, especially during the deity's Zodiac year or month. Favored Souls are slightly more likely to be born in their deity's Zodiac month than outside it. Favored souls are generally much more likely to be born inside their deity's Zodiac year than outside it. Some parents will go through great efforts to have children born in certain Zodiac years or they will take efforts to avoid having their children born during certain Zodiac years.
