Total War: WARHAMMER III

Far beyond the world and its petty wars there exists a dimension of pure, malevolent magic: The Realm of Chaos. It is a terrible place, incomprehensible to the mortal mind. It whispers promises of power, but to behold it is to be seduced by it. To relinquish your soul to it. To become it.

The four Ruinous Powers rule over this place, ever seeking to slip their bonds and engulf the world in a tide of daemonic corruption. Nurgle, the plague god; Slaanesh, the lord of excess; Tzeentch, the changer of ways; and Khorne, the god of blood and slaughter.
