The big idea
The idea of the celestial alliance is to create a background / context / milieu for stories, games, conversations, and more.
There are edges, chasms, and untold more within this cosmos. Please add to this material knowing that much of the content here is meant to serve as exemplars of place, and exemplars of people. At no point should the celestial alliance be considered one-dimensional, homogeneous, or "a singular thing". Think huge-ass multidimensional tapestry, and you about have the idea.
The Celestial Alliance is meant as a venue to explore what our future might be, shadow and light. It is also a place to explore what it is to be human (and not). It is a universe, which might be ours.
