DnD Head Canons

[Bohandas]

*When we hear about slain outsiders merging with their plane, that's in the sense of literally turning into a partnof the landscape that wasn;t there before, like slain primordial deities in many mythologies, or like the hag countess when Asmodues killed her. It just happens on a smaller scale. They might turn into a tree or a building or something (edit: or even an object)

*Inevitables are responsible for multiverse-wide price-fixing that keeps prices largely the same no matter where you are and keeps coins largely interchangable. (they're also somehow responsible for why you can't conjure gold and gems and stuff and why the method for making the philosopher's stone is lost; they suppress the knowledge of how to do that stuff)

*Every type of environment has it's own type of inevitable dedicated to maintaining it, comparable to the Anhydrut (see Sandstorm) and its place making sure that deserts keep being deserts. Lawful Neutral drhids work heavily with these inevitables

*The weave is not the source of magic in Faerun/Toril/Abeir-Toril/Realmspace, but merely stabilizes that place's naturally wild magic and makes it safely usable
