Shadowfell

The Shadowfell, a
===Darghian Rift===
In the skyline from almost anywhere on Urz, the sight of a large black line that shoots off into the sky can be seen. This physical manifestation of the Plane of Shadow is said to have originated in the very earliest times of the world and is believed to exist for a number of religious regions. It is a gate to the lands of death and historically has been moved across the land by very powerful mages. At current, the rift has settle in the province of Dargh to the north.
===Dread Realms===
A Dread Realm is a demiplane located on the edges of the Shadowfell, hidden from the rest of the planes by thick walls of mist. A Dread Realm is formed when the Shadowfell overlaps heavily with the Material Plane due to some great tragedy of mortality. Often times, a single mortal being is the focus of a Dread Realm and is given the power over the newly formed realm to serve as its Dread Lord.
