- Asmodeus is not nearly as powerful nor influental as most people think he is. There is no Pact Primeval, he never was a god, and he does not even have any sort of meaningful control over hell and the rest of the archdevils.
What he does have, however, is a vast propaganda machine across the planes that has managed to convince most of the material plane and many mortals elsewhere of these lies.
- The upper planes and many angles are actually very actively involved in the blood war, though they act mostly only to mitigate collateral damage and to protect innocents that would otherwise get involved in the conflict.
- The Wall of the Faithless wasn't created by anyone, it is just the natural endpoint for any souls without divine protection in the Realms. Most gods are extremely frustrated that some souls still end up in it, given that they offer free access to afterlives that are in their opinion obvious paradises.
- Most demons enjoy playing into the mortal stereotype that they are not as subtle or intelligent as devils, as it makes it easier to trick them.
- The Oard are totally canon and in their original timeline eventually turn into the Illithid. And I don't care how little sense that makes.
