Ethereal Sphere
From Mondarth Codex
Not strictly one of the spheres of existence, the 'ethereal sphere' is the dimension between the spheres. An extended space with no definite directions it is virtually impossible to navigate.
The only known way to navigate the ethereal sphere is using the tru spheres of existence as beacons. Losing these reference points means wandering, lost, until a new beacon is found.
