Kakophonies, also known as Cacophonies were strange and experimental psycho-sonic weaponry used by the Emperor's Children during the Horus Heresy. These were savagely powerful weapons produced from a fusion of Imperial and Xenos technology. They were able to unleash blasts of screaming discordant energy that can rupture flesh and incinerate metal, but their most terrifying ability was to open up the minds of those they touch to the horrors of the Warp. However, these weapons were also dangerously unpredictable in their early versions.
"Kακοφωνία (Cacophonia) is Ancient Greek. The literal translation is "bad sound" or "bad voice".
