Noise Marines - History: The first creation of the Noise Marines goes back to the days immediately preceding the Horus Heresy. The Noise Marines' name comes from their preference for weapons that use concentrated sound and sonic waves: the Sonic Blaster -- outwardly resembling a Bolter -- produced discordant blasts of sound; the Blastmaster -- a rifle-like weapon that produces different sonic frequencies that overpower senses and can even destroy flesh; and the Doom Siren, a loudspeaker surgically melded into the Chaos Space Marine's body that enhances his own screams into violent torrents of pure sonic force that can knock even the largest enemy off his feet.All of this sonic weaponry is descended from the musical instruments invented by the famed composer Bequa Kynska of Terra, who accompanied the Emperor's Children's 28th Expeditionary Fleet as a Remembrancer aboard the Battle Barge Pride of the Emperor during the Great Crusade. Kynska was a jaded musician always in search of further sensations to create more exhilarating and all-encompassing music, which made her an easy target for Slaaneshi corruption.After Kynska accompanied many of the 28th Expedition's Remembrancers to the temple dedicated to Slaanesh on the Xenos World of Laeran, she was touched by the Chaos corruption of that foul place and slowly sought to create the ultimate orchestral piece that she believed could capture the wondrous sounds she had heard within the Laer temple. Her ultimate masterpiece was a symphony she named the Maraviglia and which she performed for Fulgrim and all the assembled Astartes of the Emperor's Children and their support personnel within the Remebrancers' lounge called La Fenice aboard the Pride of the Emperor.To recreate the sounds she had heard, Kynska created new musical instruments whose sonic powers could also be used for destruction when employed by an individual already corrupted by Slaanesh. As the Maraviglia began, the cachophony of sound unleashed by these instruments acted as a sorcerous ritual that opened a link between realspace and the Warp and allowed the power of Slaanesh to directly touch the audience. During the "performance" it was noted that the musical instruments were able to produce effects variously disorienting, stimulating and downright murderous.Chaos mutations ran rampant through the audience and Astartes and humans alike were so overwhelmed by sensation and uncontrollable emotions that they unleashed an orgy of both sensual hedonism and the most base forms of murder upon one another. Ultimately, the music summoned five Lesser Daemons of Slaanesh known as Daemonettes from the Warp who possessed the bodies of Kynska and several of her singers and joined in the slaughter.During this part of the concert, several Emperor's Children Astartes left their seats and took up the instruments to try and keep the Chaos music playing and in the course of their untrained fumblings with the instruments discovered that they could unleash waves of destructive sonic power filled with the strength of Chaos. When the Emperor's Children engaged the Imperial Loyalists during the Drop Site Massacre on Istvaan V, some Emperor's Children Space Marines took to the field armed with these modified sonic weapons, becoming the first Noise Marines.The Noise Marines present in the IIIrd Legion soon organised themselves into a unit known as the Kakophoni which was under the command of the Legion's Third Captain Marius Vairosean. After the Heresy, the early Noise Marines took their deviant behaviour to a new level through their dedication to their patron Chaos God and over the years of bloody warfare with the Imperium have honed their bodies to possess such extreme sensory perception that nothing can stir their emotions other than the din of battle and the screams of the dying.
