They tend to live in tribes that move from area to area. The humans that live in the wastes are savages when compared to humans from the Old World. Time and space are matters of perception, and the weather can change instantly. Because the wastes are so close to the realm of Chaos, the laws that govern Order are fluid.
The area around the entrance to realm of Chaos is commonly known as the Chaos Wastes. Without magic the daemons faded back to the realm of chaos. The daemons would have destroyed the world, but the High Elves were able to create a vortex to drain most of the magic away. From this realm came the energy known as magic, but also the beings known as Daemons. The hole was located at the worlds north pole, and led to the 'realm of Chaos'.
Long ago, the inter-dimensional gate that brought the 'Old Ones' to the world collapsed, ripping a hole in the fabric of reality. This is no longer allowed in the current rules but the book has rules for using a cannon crewed by chaos dwarfs. The forces of chaos were originally represented by one army, but later was split into separated armies (Daemon, warriors, Beastmen), but could still use each others units. The book gives rules for playing with the human Chaos worshippers from the Chaos wastes, as well as background information. Hordes of Chaos is a Warhammer Army book, a supplement to the Warhammer Fantasy Battle game.
