[ +- ] The Gauntlet
Gauntlet, the: The barrier between the material realm and the Shadow Realm. The strength of the Gauntlet varies in certain areas, and even disappears completely at a Verge.
The physical world is not the only world. Existing within its same spaces, occupying the same geography, is a state of existence that is invisible and intangible to physical sensesand bodies. This state is called Twilight. It refers to any ephemeral being or thing that exists on the same side of the Gauntlet as physical beings. Twilight ghosts hover over, beside and even in the same spots as Sleepers who carelessly tread upon spectral anchors, the places to which ghosts cling.
Spirits that cross the Gauntlet and latch onto a fetter also exist in Twilight. While the occasional Sleeper might sense spirit presence as a chill or the hairs on the nape of his neck rising, he otherwise goes ignorant. Mages have a keener sense for these things. They know immediately when something strange is amiss, and can then cast Mage Sight upon themselves to identify and scrutinize the threat.
Sometimes, the strength of the Gauntlet can become so weak, the barrier so thin, that it fades completely, creating a Verge, a place where the material realm and the Shadow connect with no barrier. Material beings can freely enter the Shadow, and spirits can freely enter the material world (although the latter become Twilight, unless they have powers that allow them to materialize into bodies).
Verges are almost always temporary phenomena, opening for an evening or even an hour and then sealing again
