Because of their kind's unending need to bathe in murderous sensations, the Dark Eldar have evolved the Hekatarii, known in common parlance as the Wych Cults. Each Wych Cult is a thousands-strong organisation of gladiators that put on nightly displays of the most incredible violence; not only for the edification of the masses, but also for their literal sustenance. Such is the scale of the carnage staged by these armies of warrior-athletes that their audiences leave the arena with the glow of well-fed predators. In this way the populace is kept from full-scale anarchy -- at least, those portions of Commorragh wealthy enough to attend the Wych Cults' nightly performances.
