The Line is a strange dimension. It appears as a giant snow-covered road, with mountains of "plowed" snow on each side. On both sides of these mountains are seemingly endless oceans of ice. The Line isn't always straight, and does tend to split into multiple trails. The Line is also prone to dangerous blizzards.
