The trouble with being a god is that you've got no one to pray to.
|— Terry Pratchett, Small Gods|
It's well-known that Godville is polytheistic, but a hero usually believes in only one of them; and that is good.
By definition, a Goddess is the only smart one in Godville. Well, this is true in theory, but she is also the only one that creates, grows, guides, revives, sends to arena and generally helps their favorite hero along.
The thing is, in Godville you are the God, and it's you who has to care for your hero or he will surely get nowhere in life.
