A culture that only exists in the spirit realm or another dimension, but not necessarily in the mortal world.
'Before the Greek gods called themselves Olympians, in ancient Greek times, they called themselves Etherians, because they were so ethereal and descended from the upper-air, Aether. Etherian was a spirit culture, because it didn't exist in the mortal world, but only in the gods' realm.'
