As always, there is a religious theme to Diablo 4. We see a man praying at the start of the Diablo 4 announcement trailer, which makes sense considering it’s literally a game about angels and demons. If there wasn’t some strange religious element to the game, that would be more surprising. But it’s going to be about far more than just that. From that trailer alone we get elements of treasure hunting, ancient magic, betrayal, “forbidden” magic, and plenty of occult themes. While we don’t know a ton yet, we definitely know that it’s going to get really strange and dark.
