Ethereal Plane

The Ethereal Plane is a plane that lies directly next to the Prime Plane. To those who can travel there, it serves as a place of quick travel, and spying. It is an exact copy of the Prime Plane with no living creatures, but everything is as substantial as gas, save for lead, other heavy metals, or magical wards.

A constant fog is present, wisps extending everywhere.

Effects of the Ethereal Plane on creatures
Celestials and Fiends find that they are not quite so greatly weakened in the ethereal plane as they are on the prime plane, but they are still weakened. Hopping between the two is an effort for them.

All creatures originating from the Prime Plane find themselves able to fly upon visiting the ethereal, as well as being faster, their speed doubled.

Any creature from the Unknown Plane is incredibly weakened by its presence on the Ethereal Plane
