Flamers are Lesser Daemons of Tzeentch, similar to their Horror counterparts.
Manifested at the will of Tzeentch, Flamers resemble amorphous blobs with two arms and numerous mouths scattered around their bodies. Flamers rely on levitation to move around, although it is unclear if this is achieved via internal gases or the absence of the laws of physics in their home dimension.
Flamers are so named for the warpfire they constantly emit and utilise as their primary means of attack. Due to them being servants of the Chaos God of change, the fire produced by a Flamer does not necessarily burn what it touches, but can have any random effect. Victims of a Flamer attack may instead be frozen, dissolved, stripped naked, soaked in liquor or even severely mutated. Due to their constant energy output, Chaos Marines of the Thousand Sons legion have been known to exploit Flamers as a living power source.
The most powerful Flamers are often referred to as Exalted Flamers. These greater Flamers possess greater power and even sapience, resulting in them often assuming command over their lesser brethren.
