Choas is the name for the primordial forces that exist within the warp. It is lead by the four Choas Gods Khorne, Tzeentch, Nurgle, and Slaanesh, and is fundamentally opposed to the Emperor and his Imperium.
In the past, the Imperium has attempted to keep Choas a secret so as to minimize its corrupting influence, though that hasn't stopped various cults and uprisings from forming. However, in TTS, this has become a moot point as Choas has made itself known via the hijacked Slaaneshmas broadcast,[1] and later by the Emperor's discussion of it via public voxcast. To get around Imperial word filters, it is referred to as "Choas."[2]
The Warp[]
Beyond the material realm exists the Warp, a place where all the thoughts and emotions of soul-bearing species collect and coalesce. Physical laws break down in the Warp, making it useful for space travel, but also makes it extremely dangerous. Those without protection will find themselves driven insane, or worse, became prey to the inhabitants of the Warp, known as Daemons.
The Warp will sometimes also merge with the material realm in what's known as a Warp Storm. Most storms are temporary, but one of the largest and most dangerous of Warp Storms is the Eye of Terror; most of the Traitor legions hide out in here. The Eye of Terror is located where the Eldar empire used to be before the birth of Slaanesh. Choas' ultimate goal is to permanently merge the material and immaterial realms to do with as they will.
Choas Gods[]
The four Choas Gods are powerful warp beings that represent the pinnacle of certain emotions. They command large hordes of daemons and bend reality easily to their whims, as well as interfere in the lives of mortals for their own amusement. They feed on the emotions of mortals, just as they encourage mortals to serve them. They are:
- Khorne - God of War, Blood, Rage, Honor
- Nurgle - God of Disease, Filth, Life, Decay, Apathy
- Tzeentch - God of Sorcery, Bargains, Hope, Mutation
- Slaanesh - God(ess) of Pleasure, Pain, Excess, Debauchery
- Malal - He doesn’t exist, shut up about it
- Great Horned Rat - God of the Skaven, Treachery, and Pestilence
Forces of Choas[]
The four Choas Gods represent different experiences and emotions, and are often at war with one another whenever they lack a common goal. They are served primarily by daemons as extensions of their own will, though they are also served by mortal followers who will serve them in exchange for favor. Those with the highest favor will become Daemon Princes and become effectively immortal.
Most of Choas' servants come from the following different factions:
