The Ethereal Plane

Indicated with the Blue dotted line near the centre of the map
Not much is known over this domain, with few having ever entered it. The domain is described as a blueish void with spectral remains of ancient building high long since have fallen. Some speculate that the Godlings have their domains somewhere in this void. If one travels long enough trough the Ethereal plane, they can find themselves arriving in on one of the elemental planes.
