Well, technically, it's not really a God. Or it kind of is. I haven't decided yet.
Let's just start with the beginning.
In the setting I am trying to create, there are no such things as atoms. Everything is made out of an extremely small silk-like texture. Even metaphysical things like spirits, music, Magick/Mana/Magicka, and Reality itself.
So, I thought I would make the Chief Deity of my setting a Moth. Haven't chosen a name yet, though. Originally, it was going to be some sort of gigantic flying whale, but yeah.
I could explain some more, but I would have to delve deeper into the setting, something which isn't really completed.
Sorry if you expected something more complete, I just thought of it now.
