Sidonai - God of Sin & Wisdom
Sidonai is the most revered god in The Church of HellCake. He is also known as the devil, the lord of sin, the blood god, the shadow god, and likely has many other cool names that I've never heard of. If you want to know how to be in his favor, consult the The 7 Beautiful Sins article.
The Devil's Playground
Sidonai is the god of sin and wisdom. He can operate in the same fashion as Loki, in that he can manufacture gods and universes. But he does not merely do so just to confuse you, but to have a little fun. In one universe you may die and go to Heaven, and meet the Christian God in some humanoid form Sidonai chooses, and then he will come down and decapitate him right before you. Sidonai and his children are hunters/predators. They don't seek to rule, they seek to indulge. Your universe could be one of the ones he manufactured to serve as a playground for his children. Even if it's not, that does mean they won't visit yours, or reshape it to be added to the collection.
The Wisdom Gamble
So... even if you die, go to Heaven, and meet an all-loving God, he may end up getting decapitated. After that who knows, maybe he'll send all of you to Hell and feed you to his children. Since Sidonai is also a god of wisdom, the non-believers may catch a break. So if you want to be safe, you should probably start learning critical thinking skills before he rips out your spine and fucks your family with it.
The Children of Sidonai
Blood demons are similar to vampires. Their true form is that of a demon, but they are shapeshifters. They prey and feed on the blood of animals, including the human animal, under the cover of night. The purpose for your universe, including your existence may be nothing more than to entertain his children. You could also say they are similar to large cats, they are beautiful, dangerous, and like to play with their food. Having critical thinking skills can also allow you to win their favor and avoid being a meal. Nothing gets them more hot than aggressive stupidity, and when they get hot, they do a lot of nightmarish soul sucking.
What would a religion be without punishment? Well, this isn't quite punishment. It's more like, if they like you, they'll take you off the menu. Like a goat. If you're good little goat or human, then you get to stay off the menu, and maybe become a pet instead.
When it comes to hunter/prey, his children must follow certain rules. Animals that are deemed worthy, such as abiding by the the virtues and vices of HellCake, are off the menu. If one were to ignore this rule, then their powers may be suspended until they die in the world they are currently occupying or terminated indefinitely. So your typical Christian often makes a good snack.
And as always, remember, they're supernatural creatures and you can't disprove them. They live deeper in The Great Void than any of your other religions.
