Angron tore his way through the rend in space, stepping forth in a fountain of gore onto...
Onto what some distant part of his fractured mind recognized to be some sort of wedding reception. His blazing eyes could spot the groom, the bride walking up the aisle, and-
The Primarch of the World Eaters, Daemon-Primarch of Khorne, suddenly found himself yanked downwards by his collar, to find himself face-to-face with RAGEANGERHATREDWRATH-
"AND WHAT DO YOU THINK YOU ARE DOING INTERRUPTING MY DAUGHTER'S WEDDING?!"
Though the Primarch of the World Eaters could not prove it, he was certain that the Warmaster of the Cainite Protectorate had served as a direct conduit for his own master; there was no other explanation for the fear he had felt in the face of Cain's fury, but that Khorne himself had been speaking through the man.
And that Zerayah Cain was high indeed in Khorne's favor, if He would speak of her as "His daughter".
Angron swore to avoid her, and Slawkenburg, and the Protectorate in general in the future; some fights are just not worth it.
