CHAOS GODS
There are four Chaos Gods: wrathful Khorne, devious Tzeentch, pestilential Nurgle and cruel Slaanesh. All are jealous and prideful deities, each believing himself destined to be the supreme ruler of all existence. Yet the gods seldom lower themselves to direct confrontation with one another – such is the business of minions, not omnipotent masters.
In the Chaos Wastes, you may encounter areas that are cursed. When you enter a cursed area, the landscape itself is influenced by its current ruler which dramatically changes the way you need to play.
