With regards to the Moon, given the presence of the statue and its significance to the Ascians/WoDs, has anyone considered the possibility that it was once an actual habitable world? Lahabrea has oft referenced Hydaelyn as a parasite or cancer and it wouldn't surprise me to discover she stole the aether from Zodiark's creation and killed it to improve her own. It's an educated shot in the dark but it would explain a lot if it were the case.
