Shadowfell

The Shadowfell, also known as the Plane of Shadow, is one of the planes of existence in various cosmological models. Its purpose and characteristics evolved as new cosmologies were formulated. Other names for this plane included Shadowland, the Demiplane of Shadow,the Shadow Deep, and simply Shadow. It existed as sort of a counterpart to the Feywild, in the sense that it was a reflection, or "echo", of the Prime Material Plane. Unlike the Feywild, it is a bleak, desolate place full of decay and death. Melaskari, Goddess of the Undead makes her Queendom here in the city of Duskthorne, a city controlled by her worshipers. The city functions as a waypoint to the afterlife, souls find themselves appearing in the city proper and are ushered into the Astral sea in which they eventually find themselves reaching The Endless Road. Souls that escape this journry or are tricked into staying in the city of Duskthorne become servants of the Undead God, Melakari.

Geography

Truly a place of shadow, the lands in its realm are never found under light; the Shadowfell lacks a sun, moon, or even stars. This leaves the sky empty and black while the world is devoid of color, leaving everything in shadow. It is an ever changing plane and it has been found almost impossible to map. As a reflection of the material plane, the Shadowfell holds major landmarks as a part of it, but they are often distorted in some way shape or form. The ground is dry and cracked with mountains strewn throughout, its oceans are endless bogs and swamps.
