Phrenesis

"This shall be the living heart of our divine enterprise. It is here we shall deliver our Great Message to the Galaxy. Here, we shall make Order and Chaos, Sanity and Madness, Clarity and Nihilism, indistinguishable. We shall make these things one and the same, for one and the same are they. Let this be a monument not to any one superficial god, but to the Primordial Truth in it's fullest glory."

- Azunar, M31 .

Phrenesis is the Throneworld of The Dark Priesthood and the most prominent recruiting world for the Host of the Truthbringer. Established in M31, Phrenesis is the single most potent monument to Empyrealism in the Galaxy, and it is from here that the Priesthood's Cardinals plot the enlightenment of Mankind.

Foundation
Following the Horus Heresy, Azunar, the Ruinous Apostle, called dozens of minor warbands, mutant hordes, cults, and covens to the sparsely inhabited daemon world of Phrenesis, deep within the Dread Clouds at the Galaxy's heart. There, a tournament was held against the many champions, and the survivors became the founding leaders of the Dark Priesthood. This was the 1st of 14 conferences, where Warband leaders discussed their progress in bringing Empyrealism to Mankind.

Geography
Phrenesis is a sprawling, honeycombed Shrine World, with great, labyrinthine forges beneath the surface. Inhabited by billions of mutants, witches and heretics, the crowded world is dominated by several prominent structures.

About
(Add your own!"Phrenesis is one of the rare Daemon Worlds that does not mindlessly break and enslave the masses. A man is more useful educated than stupid, free than enslaved, and alive than dead. Phrenesis does not want hordes of dumb masses: here we shall cultivate every Soul we find, and equip them with the skills needed to burn the hated Galaxy to ash"
