Devil of Gifts
Exploiting the addictive failings of mortals and the simple delights that become desperate desires. Sonova uses temptation as a weapon. If fighting should ever come, they will let others do the fighting for them, promising gifts to either victor.
She sends out devils under her command, her favorite are succubi and incubi, to the powerful and the weak alike. She offers them “rewards” or a “taste.” The first is free, a simple thing to part with but nothing that will ever last long, and nothing that will really resolve their problems. The best gifts for Sonova are the ones that don’t resolve any problems, that create problems but leave people feeling better. Each successive gift becomes more and more expensive as she starts to dig into her victims. Gradually she will start to demand gifts in return, then acts of deprivation and obscenity, and then sacrifices. More and more acts for the same amount of the original gift.
With enough time spent under her influence, her victims will happily give up their souls and the souls of everyone around them in exchange for more of her “gifts.”
