Noise Marines - Noise Marines in the Screaming Vortex: The Emperor's Children are perhaps the most depraved of the Traitor Legions to venture into the notorious Warp-realspace interface known as the Screaming Vortex on the boundary between the Calixis Sector and the Koronus Expanse in the Segmentum Obscurus. Many journey to this turbulent realm to sample firsthand the unique worlds and vile delights of its denizens, while others harbour unspeakably cruel designs for those wayward souls who fail to escape them. These deranged warriors undertake such despicable pursuits with complete disregard for the Vortex's many dangers and eagerly brave all manner of foes in their unending quest for excessive indulgence.Though small warbands of Emperor's Children are not uncommon when it suits their purposes, lone members of this abhorrent Traitor Legion are generally the norm. The most common of these are Noise Marines, whose insane yearning for the deafening clamour of battle leads the slightly saner denizens of the Vortex to avoid dealings with them if at all possible.Heretic Astartes from other Traitor Legions have also attuned themselves to similar auditory excesses, equally as devout in their pursuit of Slaanesh's gift of song and equally as deadly. Often such encounters end violently or -- if the victim is particularly unlucky -- the Noise Marine might instead take the miserable wretch alive. The destructive power of these fallen Space Marines cannot be denied, and many amongst the Heretics of the Vortex deem the benefits of harbouring them well worth the risks.A Noise Marine in the Screaming Vortex can indulge in a plethora of uniquely vile experiences and sensations in order to assuage his unrelenting yearnings. Yet, of the many temptations that await them within this turbulent realm, the lust for auditory stimulation is the most enticing of all. Whether achieved through pitched battle, arcane devices, or the abilities of one of the Screaming Vortex's inhabitants, Noise Marines go to any lengths to attain their desire and are an increasingly common sight among its many denizens.The following are some examples of the many pursuits a Noise Marine might undertake in his continuous quest for the most extreme excesses:Cacophonous Chorus - Disdaining all thoughts of material gain or honour, these servants of Slaanesh pledge their allegiance to whichever Chaos warbands produce the most frenzied clamour before eagerly adding their own destructive notes to the terrible din. This eccentricity often causes the band to change sides multiple times throughout an engagement as the roar of battle ebbs and flows. If the noise is pleasing enough, they might even turn on their would-be allies after the assault has ceased in order to delight once more in the battle's cacophonous fury.Xenoticants - There are many forbidden xenos artefacts and devices within the Screaming Vortex capable of bestowing indescribable sensations on all who dare wield or even look upon them for any length of time. Noise Marines frequently encounter such items in their travels, and many even develop a taste for these exotic delights and inhuman vibrations. Yet their pleasure often turns to obsession as these warriors attempt to contrive ever more imaginative and novel ways of incorporating their discoveries into their ceaseless indulgences. The other inhabitants of the Screaming Vortex refer to them as Xenoticants, and their frantic mania can be either a boon or a bane to those who become entangled in their endless passion for additional relics and alien sensations.Choir of Aberrance - These cruel Noise Marines demand tribute in the form of slaves, which they then incorporate into their own horrific glorifications of the Prince of Pleasure. Each captive is fitted with a bizarre array of sonic amplifiers and Vox speakers, which cause the recipient great pain and amplify every tortured cry and terrified gasp to skull-shattering heights. Thus prepared, these pitiful creatures accompany their masters into battle, staggering behind their captors in vast processions bound together with golden chains each adorned with savage and delicate hooks. There, the many cries of intolerable agony, encouraged with blows from cruelly barbed and toxic lashes, rise together in screeching and discordant adulation for the many pleasures of Slaanesh.
