I love how in the old lore of they were slowly rejuvenating their planet back into a lush paradise after nearly destroying all of it.
They had a nature religion and treated the entire surface as sacred ground so they built floating cities and only people with roles related the restoration would go the surface.
Tragically, their planet was entirely killed during the NJO series and the species who worshipped their planet were now nomads using their terraforming expertise to restore the planets of other species that were still capable of being saved.
