So I'm trying to work on my story about my antagonist but I'm really struggling. He is not really a specific entity, he's a mythological shadow god who is trapped on a planet on the far edge of the universe. Due to something that the protagonist does, the antagonist is able to sort of escape and influence people on other planets to bend to his will of destruction. I have managed to do his profile as I have the mythology of his origins down pat. But I have no idea whose point of view to write the story about him from. Any thoughts?
