The forces of the Ruinous Powers of Chaos, the Great Enemy, are an ever present threat. They exist all across the galaxy, striking wherever their convoluted and sinister plans require. Though the four Chaos Gods seem to have existed since time immemorial, the traitorous Legions have only existed for the last few millennia. Even so, more and more loyal members of the Imperium are swayed by their dark and vile means and their numbers draw ever larger.
There are four gods of Chaos
Khorne – God of Combat, Bloodshed, Skulls, and Honour.
Slaanesh – God of Lust, Ecstasy, Pleasure, and Love.
Nurgle – God of Gluttony, Disease, Death, and Life.
Tzeentch – God of Fate, Mutation, Lies, and Knowledge.
Underneath each of these gods are hordes of daemons, waiting to be released from the Warp to consume and destroy all of reality. To aid in their plots are the Legions, the forces of mankind that have forsaken the Emperor for the Dark Gods and wish ruin upon the universe. The greatest threat to any being is the one that strikes from within itself.
