A Lord Kakophonist of the Emperor's Children Legion unleashes the sonic devastation of his twin Screamer Pistols and Doom Siren.
A Lord Kakophonist is an Heretic Astartes Chaos Lord of the Emperor's Children Legion or other Slaaneshi Chaos Space Marine warbands who commands a choir of Noise Marines. Lords Kakophonist are masters in the use of Sonic Weapons, so skilled that they can infuse such weapons with the strange powers of the Warp.
Role[]
Some of the commanding Chaos Lords of the Emperor's Children Legion and other Chaos Space Marine warbands dedicated to Slaanesh immerse themselves in the rapturous acoustic devastation of Sonic Weapons, guiding choirs of Noise Marines as one of the Lords Kakophonist.
Where their counterparts among the Lords Exultant fight with their Power Swords and skilled tactical minds, Lords Kakophonist expertly orchestrate an overwhelming tirade of sonic destruction so loud it manifests strange eldritch phenomena from the Warp, quaking the very souls of their enemies.
Lords Kakophonist represent the absolute pinnacle of their kind, and it is said that they can detect mystical acoustic vibrations that exist in fluctuating dimensions within the Warp. Few Noise Marines can reach such an apotheosis of sensitivity, and this allows Lords Kakophonist to lead other Noise Marines into battle.

An Emperor's Children Lord Kakophonist is a powerful Heretic Astartes Chaos Lord dedicated to the use of Sonic Weapons.
Surgically sculpted and empyrically warped to a greater extreme than standard Noise Marines, the flesh and power armour of Lords Kakophonist have grown into whorls and membranes that focus and distort sound waves. Strange phenomena gather wherever they go, such as rhyming whispers, painful spikes of noise, and echoes of unease that are infused with lascivious portents. Their Doom Sirens are melded irrevocably with their flesh and armour, magnifying and twisting every sound the Lord Kakophonist makes. From the whir of their armour to their own breath to even their own heartbeat, everything is projected in a non-stop aural barrage that thrums out from them.
The constant songs of Lords Kakophonist are tinged by the energy of the Warp and the Daemonic. This noise weakens physical matter, shaking the barrier between the Materium and the Warp itself. In battle, their songs can shatter bone, fortress walls, and flesh. Besides their Doom Sirens, they also go into battle armed with twin Screamer Pistols.
