The Great Wheel Cosmology as an "assumed part of a D&D world"

[Glyfair]

In the beginning, there was a pie. And from this pie formed many worlds.

I don't want to see the Orc that's guarding THAT pie!

 

[mhacdebhandia]

The "Great Wheel" cosmology has been an explicit part of most official D&D worlds

Completely untrue, but I have demonstrated this point effectively elsewhere on EN World, so I won't be following this thread.
