Astral Plane that are known to possess gravity or normal time flows. Part of Baldur's Gate II: Shadows of Amn takes place on the Astral Plane. Trenton Webb for Arcane magazine comments that A Guide to the Astral Plane "breathes life into what had hitherto been little more than a planar motorway. Essentially infinite and filled with few 'solid locations' or indigenous species, the Astral Plane should by rights be a dull place. Yet with some deft imaginative touches and sleight of logic, the guide transforms this dead zone into a wonderfully different 'world'." He adds that "By expanding the accepted 'physics' of the Astral plane and applying classic Planescape thinking, the Silver Void is made solid and comprehensible." Ethereal Plane The Ethereal is often likened to an ocean, but rather than water it is a sea of boundless possibility. It consists of two parts: the Border Ethereal which connects to the Inner and Prime Material planes, and the Deep Ethereal plane which acts as the incubator to many potential demiplanes and other proto-magical realms. From a Border Ethereal plane a traveler can see a misty greyscale version of the plane from which they are traveling; however, each plane is only connected to its own Border Ethereal, which means inter-planar travel necessitates entering the Deep Ethereal and then exiting into the destination plane's own Border Ethereal plane. Many demiplanes, such as that which houses the Ravenloft setting, can be found in the Deep Ethereal plane; most demiplanes are born here, and many fade back into nothingness here. Unlike the Astral Plane, in which solid objects can exist (though are extremely rare) anything and everything that goes to the Ethereal Plane becomes Ethereal. There is also something here called the Ether Cyclone that connects the Ethereal plane to the Astral Plane. In the 3rd Edition, each Material Plane is attached to its own unique Ethereal Plane; use of the Deep Ethereal connecting these Ethereal Planes together is an optional rule. Plane of Shadow A fictional plane of existence in Dungeons & Dragons, under the standard planar cosmology. A dimly lit dimension that is both conterminous to and coexistent with the Material Plane. It overlaps the Material Plane much as the Ethereal Plane does, so a planar traveler can use the Plane of Shadow to cover great distances quickly. The Plane of Shadow is also conterminous to other planes. With the right
