The Beasts of Chaos are coming soon with something called the Turnskin Plague, which appears to make the beasts even more monstrous?

As the power of Ghur swells, a supernatural malady of mutation and devolution is sweeping the realms. Known as the Turnskin Plague, this unnatural flux is carried on campfire tales and spread through dark rituals, causing unfortunate victims to start braying, mewling, and making themselves at home in styes and stables.Many of those afflicted begin to mutate into gor-kin themselves, and are driven out into the wilds by their fearful neighbours – until a rampaging Brayherd sweeps them up, anyway. Life isn’t great for these half-beasts – the true beastmen name them “gaves” and “turnskins”, tormenting any who can’t prove their strength.Whether born or made, this swell of bodies empowers the Beasts of Chaos all the same. The influx of numbers has seen many herds reshape their primal hierarchies through vicious infighting.* Plenty of new Beastlords have emerged from this bloodbath, with some claiming to be descended from the primordial Sire of Ruin himself.
