Shadowrun: Razor's Edge
The last major eruption of Mount Rainer sent tons of ash pouring down on the south and eastern parts of the Seattle Metroplex. In the aftermath an earthquake also rocked the area, creating a large chasm called the Razor. More than a mile long and hundreds of feet at its widest point the land surrounding remains precarious and unstable. Mists enshroud the bottom of the chasm and give off a ghostly blue light at night. Only the most desperate or foolhardy venture close.
