Given that it may be a living being, does anyone get the feeling it may be somewhat related to the Doomtrain? Since it was hinted in the Rising event that there might a Doomtrain minion, and since that carried the souls of people to the underworld, might it not be that the Void Ark in XIV is a similar construct in that it carries the Mhachi black mages in a comatose stasis as an anchor to remain floating in the Sea of Clouds and Hydaelyn as a whole?
