The Outer Planes are the in-between places, lands not of the prime material plane, but not the realm of the dead. Here is where we see places like Sigil, the elemental planes, planes created by powerful wizards, etc.
Ascendant campaigns can view previous versions of their pages, see what has changed (and who did it), and even restore old versions. It's like having a rewind button for your campaign.
We've already been saving your edits, so if you
