Daemons are demonic creatures in Games Workshop's Warhammer and Warhammer 40,000 settings, hailing either from the Chaos Wastes of the Warhammer World, the void between the Mortal Realms or the immaterial realm of the Warp, and are among the most dangerous creatures to both mages and psykers. Daemons are almost always bound to one of the four chaos gods, though there are exceptions
Daemons of KhorneDaemons of Khorne are ruthless killers who will try to outdo each other in their acts of cruelty to an opponent. Daemons of Khorne are also the closest in appearance to traditional demons, generally sporting cloven hooves, red hides and horned heads.
Daemons of Nurgle
Daemons of Nurgle are disease-ridden beasts who work to spread disease throughout the universe. These daemons are usually disease ridden creatures that resemble bloated corpses.
Daemons of Tzeentch
Tzeentch's daemons are powerful sorcerors and shapeshifters, rarely having the same form as another of the same demon. As such, most of Tzeentch's daemons appear to be shapeless blobs, with only a few exceptions.
Daemons of Slaanesh
Slaanesh's daemons are mostly hermaphrodites, meaning that they are both male and female at the same time, just like Slaanesh himself.
Not all daemons are aligned to the Dark Gods of Chaos. Some, such as the Fury and Verminlord, are devoted to either Chaos Undivided or one of the minor Chaos gods, whilst others, like the Seraphon or Living Saint, are "daemons of order," creatures that appear to be daemons, yet do not align themselves to Chaos in any form.
