Even a light source that only put out shadowy illumination, like a darkness spell or a lantern burning shadowlight oil, could be seen up to five times its range of illumination. On the other hand, although it would not illuminate as far, any light source on the plane could be spotted at a distance of up to ten times its normal range of illumination, such was the contrast to the constant gloom, similar to a star in the night sky. A light source only illuminated half the distance it normally would, flames and fires put out less heat, and spells that dealt with light or fire were less predictable and prone to failure, whereas shadow spells were enhanced. The most striking and immediate impression a visitor to the Plane of Shadow experienced was the lack of color and light no sun, moon, or stars adorned the vault of the inky black sky, and all things looked as if the color had leeched out, leaving nothing but black and white, which in the dimness were more like "dark black" and "light black".

During this time, until the Second Sundering, the parallel plane became a place from which necrotic energies and shadow magic stemmed. Shar called her new creation the Shadowfell. Such was the power of this combination that the souls of the dead began to be drawn to this altered plane and had to pass through it before reaching their final judgment on the Fugue Plane. The Elemental and Energy Planes collapsed into the Elemental Chaos but not before Shar managed to manipulate some of the necrotic energies from the Negative Energy Plane and inject it into the Plane of Shadow. In 1385 DR, the Year of Blue Fire, Shar succeeded in engineering the murder of Mystra by Cyric, plunging the multiverse into years of upheaval and chaos called the Spellplague. The desolate landscape of the Shadowfell. Intrepid travelers could still reach other universes by traversing the Shadowfell and locating the border with an alien world such as Oerth for example.

Rapid movement between points of the Prime were still possible by stepping into the Shadowfell and skirting the edge-referred to as the Shadow Fringe -before stepping back into the Prime, but arriving at a particular destination was much less precise than before. The Plane of Shadow was no longer connected to the Ethereal Plane, even though it was coexistent with it. The entry and exit point of a vortex were unpredictable as was their duration, lasting a few days at most.

Naturally occurring intermittent portals called vortices appeared between this plane and the Material Plane in seemingly random areas of heavy shade or darkness. In the World Tree cosmology model, the Plane of Shadow was seen as an infinite plane that coexisted with the Prime Material Plane-touching it at all points and having the same basic geography -but only accessible at night or from shady areas using the shadow walk spell. In later and revised versions of the Great Wheel cosmology, such as the one following the Second Sundering, the Shadowfell was considered a parallel plane, or an "echo" of the Material Plane, coexisting with it along with the Feywild.

Very little was known about the Demiplane of Shadow other than it was a dim and dismal place. If any were brave enough to cross the Demiplane of Shadow, it was possible to find the borders of other planes of reality. Clerics could use the plane shift spell to travel to this plane. Wizards could shadow walk directly to the edge of the Shadowfell and travelers could use this plane as a transitive plane to traverse many Prime Material miles/kilometers very quickly. For those traveling through the Ethereal Plane, the "curtain of vaporous color" for the Demiplane of Shadow was the color silver. The largest of these was called the Demiplane of Shadow, and was made up of both positive and negative energy in equal measure. Demiplanes formed out of the proto-matter that ebbed and flowed about the Ethereal Plane, creating a finite plane with its own Border Ethereal whenever a critical mass was achieved.
