From the boundaries of reality, the Chaos Gods, also known as the Dark Gods or the Ruinous Powers, look upon the Mortal Realms with covetous eyes. It is their nature, their all-consuming purpose, to destroy. Relentless and unstoppable, all of their incomprehensible energies are directed to collapsing reason and perverting order.
In the ever-changing Realm of Chaos the Dark Gods rule supreme. Their rivalry is eternal, each god seeking dominance over his brothers. These dark siblings now number five: Nurgle, Father of Plagues, Khorne, the Blood God, Tzeentch, the Changer of Ways, Slaanesh, the missing Prince of Pleasure, and the recently ascended Great Horned Rat of the Skaven.
