America’s Shadow

According to an answered readers question, it is unclear if the shadow realm is a singular place, or a multitude of places that are mistakenly grouped together. Apparently, some mirrored surfaces do not reflect our worlds, but instead allow the viewer to look into another. Such mirrors can in theory be used as doorways, this can be prevented by replacing and destroying affected mirrors.

Creatures from the Shadow
Some of the monsters from the Shadow are:


 * the Unwelcome Riders
 * the Unbidden Homesteaders
 * The Labyrinthine City and its monsters
