A Tour of the Planes
The planes await!
For each of the Prime Material Planes, there is some mythology of how things came into being. Almost all of them involve a progenitor race, a mighty overgod, or some similar construct, crafting the plane and its inhabitants after some grand design. However, some planar scholars with too much time on their hands wonder if the Multiverse itself wasn’t similarly created. Such an undertaking would surely involve beings of such limitless cosmic power as to defy all categorization. It goes without saying that they would have known what they were doing.
To put it simply, mistakes were made.
This is a tale of the history of creation, hidden away from covetous eyes for untold eons, and of the dangers that yet threaten to tear the Multiverse asunder.
