When the Murderval of Chaos was defeated upon the Eldar world of Lohiac, Ssair the Gleamling was in a serious predicament. The Dark Eldar had denied the Daemons entry to the webway, and left the host bloodied and humiliated. With Ssair's power and influence waning, it was unsurprising that a rival should seek to gain prominence in his stead - this was Corflich Loatheheart, a beautiful and cunning Daemon Prince sworn to Tzeentch.
With the deft manoeuvring so typical of Tzeentch and his minions, Loatheheart duped the Greater Daemon of Slaanesh into yielding power of the Murderval into his stewardship on promises that it would be returned once it had claimed its millionth soul for Tzeentch. Of course, the oaths of a Daemon Prince are a dubious thing and it was not long before Ssair found himself imprisoned within the Impossible Fortress, and the Murderval fully under new management.
The first act of Corflich was to strike out against the agri-world of Dortun, where the populace were eradicated in three nights of bloodshed and debauchery. Upon the Tau sept world of Vior'la they stole away three hundred Fire Warriors and deposited them within the Garden of Nurgle, much to his delight (and their short-lived horror).
