(from the back of the book)
The liberated Great Old Ones will teach people new ways to scream and kill, to exult and have fun. And the entire earth will be aflame in a purgatory of ecstasy and freedom!
In the year 5000 the earth is a hell flooded by cosmic horror. The last civilized people live behind the protective walls of the cruel kingdom of Tsan Chan and have found a way to adapt to the situation and to form unholy alliances. This bizarre world is described in detail.
The "Stillwater Rapids" adventure (with pre-designed investigators) offers the ideal introduction to the distant future, when cruelty and madness reign over the earth.
