One thing thats notable in Baldur's Gate 3. Devils can pop in and out of the world, seemingly going back to hell and then returning to the mortal world as they need to to conduct their business.
But in 5e the vast majority of devils have no such capabilities. No teleport and no plane shift. So is the assumption there is some infernal portal in the world, and the devils are hoofing it to get to where they want to go?
