Matoran society concepts in my head that I need to flesh out more:
Group of Le-Matoran traders who live exclusively on a fleet of airships that sail wind currents throughout the MU. All of their trade with the world below is done via cranes and elevators, it's a point of pride for them that they never touch the ground
Village of De-Matoran who live in a cave system specifically carved to have perfect acoustics inside and perfect soundproofing from the outside. Their culture is built around a never ending musical performance that they all take turns maintaining, which can be heard with no distortion or muffling anywhere in the cave system.
An outpost of Ce-Matoran who live around a natural outcropping of memory crystals, the main job in their village is to commune with the crystals and try to interpret the memories they find in there, as well as cultivating new experiences and memories for them to add to the crystals themselves. Some of these crystals form part of the GSRs long term data storage, with many of the memories they see in the crystals being observations Mata Nui made of the other worlds he visited.
