Of the many diverse Clans that engulf much of the Under-Empire, there are none so powerful both militarily, politically, and influentially as the Four Great Clans. These ancient Clans consist of the Warlock-Engineers of Clan Skryre, the fanatical Plague-Monks of Clan Pestilens, the Assassin-Adepts of Clan Eshin and the mutated War-beasts of Clan Moulder. These Clans hold the greatest occupation within the Under-Empire, and whose wealth, power and influence has the potential to change the political and social landscape of the Under-Empire on a whim. Their power extends so much so that the leaders of each Clan occupies a seat within the Council of Thirteen.[1a]
