Elemental plane
The elemental plane is really one connected space, but is divided by convention into either 4 or 12 smaller pieces, what are usually thought of as the elemental planes (plural). Here, raw, un-aspected aether is given form and purpose, to be conveyed back to the Mortal plane to continue the cycles of life. The elemental plane is co-incident with the Mortal in all places, but portals connect areas throughout its volume so most portions of the elemental plane are accessible regardless of where Quartus is in its orbit. The influence of particular elemental aspects wanes and waxes throughout the year based on orbital position, giving rise to the seasons in the Mortal plane. Conversely, the nearness or farness of the various planets (but mostly Quartus) give rise to the "seasons" of the elements--Conjunction occurs in a particular place when Quartus is "near", and Opposition happens when Quartus is on the other side of Eua. Thus, Conjunction in the Plane of Flame is Opposition in the Plane of Ocean and vice versa.
