991.M41: The Plundered Flesh of Pech
After capturing not only countless Tau upon Vigos but also the mercenaries with which they bolster their cadres, the Prophets of Flesh discover that the Kroot are able to learn and even evolve purely by selectively devouring the fallen. To appropriate such an ability would be seen as a coup even amongst the Haemonculi. Before long, the Prophets of Flesh have opened up a webway gate upon the Kroot home world: the humid jungle planet of Pech. The Tau, fiercely defensive of their empire’s mercenary allies, counter-invade in force by mobilising twelve Hunter Cadres to scour the jungle clean. The unfolding battle ends abruptly when the Prophets of Flesh withdraw, their Raiders straining to the point of collapse under the weight of the Kroot corpses they have stolen. Though the Tau propaganda machine celebrates a great victory, the Dark Eldar have what they came for. They leave a message behind, spelt out in the bloody corpses of their victims. It is loosely translated by the Water caste as the phrase ‘Welcome to the Feast’.
