My interpretation is that the world is just the normal world, and the demi-plane thing is just a standard player-counter. Strahd came in, made a horrible pact with "dark powers," and then the dark powers removed Barovia from the world - not because it was ambiguous where Barovia came from, but as a complete railroad to make sure players can't leave with tricky magic. Teleport would solve the "you can't leave" problem in a heartbeat - but it doesn't work if you're trying to leave the plane. It's more of a "gotcha" than a land ripped from a world of gothic horror that otherwise exists somewhere. The point is that Barovia is gothic horror because Strahd made it so, and kept it that way. If Strahd had been an evil drow from FR who made a pact with the dark powers, Barovia would look different - but still be on another plane to confound player- er, I mean adventurers who were sent there.So apparently Barovia was enshrouded my mists, ripped from the world it was part of, and is now a demiplane.
Do we know anything about the world Barovia was once part of? Are there any supplements or Dragon articles about it? From reading Curse of Strahd I am getting a sense that this world was sort of a low-magic, low-monster world, where demihumans are uncommon in human lands, and closer to a Renaissance social and tech level. But do we know anything specific?
