Editing Monte Cook's World of Darkness (section)

=The Intrusion Point=
Canonically, the Intrusion Point is a 500 mile spherical "impact point" that occured in Upper North America, although the setting provided advice on how to handle it placing it in other areas and the resultant effect it would have on the setting - people will care much less if it happened in Antarctica or the Sahara, but ''way'' more of it happened in Washington DC, to say nothing of the damage it would do to civilization indirectly by manifesting at sea or up in the sky. It's broken into three parts.

The "core" of the Intrusion Point is known as the Conflagration; a 150-mile-radius area that extends almost to Minneapolis and encompasses the small cities of Sioux Falls, South Dakota, and Fargo, North Dakota. In this place, reality as humanity knows it simply doesn't exist; you have an eternal maelstrom of swirling energy, churning matter and things for which we don’t have names or definitions. Inorganic matter in this region is in a constant state of flux, warping and changing state from gas, liquid, solid and energy. Needless to say, you go in, you don't come back out.

Surrounding the Conflagration is the Annihilation Zone; the 100-mile swathe of land ravaged by earthquakes, insanely violent weather, and the concentrated Nightmare Wave from the creation of the Intrusion Point. The churning of the Conflagration continues to spawn those same phenomena, which combined with the random and unpredictable warpings of reality here makes it a hellish apocalyptic landscape, inhabited only by soldiers looking to contain the Intrusion and those too dumb, deranged or driven to leave. The Annihilation Zone includes Minneapolis/St. Paul, but not quite Omaha or Rapid City.

Finally, surrounding the Annihilation Zone are the 250 miles of the Haunted Lands, a region that encompasses Kansas City, Denver, Winnipeg and Chicaco. Whilst still plagued with unpredictable weather, sporadic earth tremors and the occcasional monster outbreak, it's far more hospitable than the Annihilation Zone, and as a result there is still life here.
