[@Vec] I understand that, but as I said, some systems like The Occult had direct influence of the god.

To give an example using my character:

If Ilunabar died I imagine stuff like the Raka and her kind of Shamanism would go on. Stuff like the Grand Parade however would be different.

And I think there is some aspect of Magic that is like the latter. Though it can be explained, like minor demons taking over The Occult's sacrifice deals or an automated system being created.
