I have this mental fanfiction that every god has a way to be killed, and when you kill them you can get things from them.
For instance, the one that I refer to the most often is Ben Franklin using a kite and a key to slay Zeus and to steal electricity from him.
And then of course there’s Prometheus who intentionally and willfully laid down his own life so that humanity could have fire.
But there are more gods than there are words to describe them.
What other gods have we claimed existed, that we humans have likely slain, and what do you think we got from them?
Oublievish, god of the forgotten
We cast him into darkness so deep that the light could not reach him, and he ceased to be. From him, we stole the ability to forget. And then we used that ability to erase our memory of our crime. Now, no one knows he even existed.
