That's what I was thinking about but Bahamut isn't really related to astral and is usually a non elemental summon, well he do have shiny skills with Tera Flare and Akh Morn but nothing in the game really points that way. It could be that non elemental can also be considered as an element or a combination of all elements and once all elemental calamities are unleashed, then the only thing remaining to be unleashed on the land of Hydaelyn's light is the Zodiark's darkness.

There is still a lot we don't know about these calamities, except that the mortals are awakening more easily to their spiritual parts and possibly to the echo, maybe the last calamity will completely break the separation between the aetherial realm and the physical realm.
