Halfway Through the Final Curtain
The Shadowfell is the gloomy reflection of the natural world. It is a plane dimmed and dulled by a pervasive and insidious pall. The home of the dead, the realm of the forsaken, a haven of the lost and the twisted, the birthplace of wretched creatures famous for their grief and sorrow—the Plane of Shadow is all this and more. Familiar landmarks, peoples, and places are changed, as if born from half-remembered nightmares or perverted by fear and doubt.
Many clerics and cultists of dark immortals consider the Shadowfell an ideal place to create undead servants. All too often, the spellcasters who create such dark servants abandon their creations to the surrounding shadowscape when their purpose is accomplished, once control is lost over the undead, or even as a matter of pure malice.
