Wait, shot down? I thought the spiritual soup idea just needed a bit of work. Not entirely shot down....

It's not been shot down. [@Kho], stop being a silly billy.

A large group of Shaman want more, for their people. Dealing and binding with Djinn does not cut it anymore, and so they all gathered around a ritually prepared girl and sacrificed themselves so their essence was siphoned into the woman. Some Shaman had Djinn, some had just dealt with Djinn for a long time. the large number of Djinn-touched souls mingled inside her and condensed into a strange spirit of great power, making the woman host a Demi-God.

This can be made to work. We're generally pretty encouraging of expanding upon the lore of the world, but if you'd like to tie it into existing stuff, you've got some points to work from:

Djinn, as they exist right now, haven't been known to mess around with souls. Changing that would alter their flavour a bit, but it's certainly not impossible, especially if you add in a dash of other power sources. The most obvious one for making a demigod is for one or more actual gods to be in on the ritual. Then you would have a character actually identifiable as a kind of parent. Alternatively, you could find an artefact lying around to tie you to some power, or even some weird occult ritual. Any good contrivance will do.

Basically what I'm saying is your origin story doesn't fly in the face of the established lore. However, it's a bit difficult to help you make it work for your character in particular without a CS to work off to get a feel for it.

As for what BBeast was referring to with where you intend to take the character, we just want to make sure that you won't disappear after completing your first post due to not knowing what to do next. It's worth thinking about a general direction to take your character, no need just now for anything too complex or deep.

Let us know once you're ready to show us more :)
