What is the most unique feature of your homebrew world/campaign setting?

During the early ages of the world, the gods of the natural magics persecuted mortal wizards, viewing their powers as unnatural as they started to eradicate nature to build civilization.

After years of being persecuted, the wizards drained power from the plane of fire to escape to space, shattering the pangea continent and permanently damaging much of the material plane. The elemental plane of fire is now a wasteland of dust, and the plane of earth was shattered into effectively a vertical asteroid belt.

Our campaign takes place four ages later. Unbeknownst to the people of this time, the wizard renegades of ages past have lived up in the Villa Straylight, at the top of the stairway of stars, in a sea of asteroids and cosmic dust. In this "beta" material plane they've been involved in their own affairs, likely changed after centuries of exposure to the outer realms. Only now are they starting to take an interest again in the world they left behind...
