Alternate Worlds of D&D: Through the Editions

[Ruethgar]

By cannon, does WotC ever say what happened to their alternate worlds, particularly thinking about when the Great Wheel got messed up. Did Ao have any affect on the shadow lord things of Ravenloft? Did Athas just ignore the Spellplague and remain unaffected by the mortality of the gods? Did the tumult unseal and merge worlds hence why Castle of Strahd is available?

By Canon?? I seriously doubt it!!

My group for years used a setting that included 3 hollow planets orbiting the same sun. Mystara/Hollow World, Faerun/Athas, and Krynn/Greyhawk. Great fun until we begin to slow down :-(

Each setting as been basically considered independent. Then of course you also have to consider editions. Greyhawk basically goes all the way back to OD&D ;-)

Canonically, Athas does not even connect to the other settings, even via Spelljammers. So it wouldn't be affected by anything happening in other worlds. It's too remote. The Spellplague was local to Toril's "crystal sphere" and had no effect on anyone else.

However, during 4e's run, there was a series of novels called "The Abyssal Plague", which was an event that went through several worlds, to include Planescape, Points of Light (4e's core world), Forgotten Realms, and Dark Sun. It is, to date, the only even to cross over all those settings so far.
