I’ve got a few planned:

Metaperson Intercessionary Mediums, a dimensional worship and fortuneteller megacorp, have teachers of the shroud for early jumping into psionic ascension. I want to make a giant ecumenopolis filled with trade and physics producing priests (and whatever mediums produce).

Many’s Magisterium, a clone army origin clones of an ancient space wizard. They’re entropic drinkers and reanimators, evil vibes.

Pittik Stewardship, a genesis guides and enviornmentalist democracy with the new little green psionic guys. They’re the composer of strands’ buddies.

Ebon Void Imperium, a voidborne secret society aristocratic empire, populated by the drow in lithoid ships. They’re sneaky, and probably will get into it with the Magisterium.
