Black Crusade (2011), p61 — Sorcerers in the Vortex

Sorcerers within the Screaming Vortex show their devotions to the Ruinous Powers in a variety of different ways. Some travel beyond its boundaries to aggressively recruit new followers to the ways of Chaos, thus granting their cruel sponsors more followers. Others choose a path of devotion to a particular deity, embracing everything that lord offers. Yet others devote every moment of their time to uncovering lost secrets and discovering new information. For these Heretics, the source of the lore is far less important than the knowledge and the power it represents.

Plague Priest of Mire: These Heretics are dedicated to spreading the influence of their dark sponsors through the gift of his pestilence, making their home on the pestilential world of Mire deep within the Vortex. Through their link to the Immaterium, these potent psykers invoke the glories of the Lord of Decay upon their unwitting opponents. As the Dark God's diseases take hold, the Plague Priest's foes often become the latest additions to his army. As these new followers embrace the ways of Chaos, the Sorcerer's potency grows with additional blessings from his dark sponsor.

Sorcerer King: In some cases, a Sorcerer seeks to hold worldly power in conjunction with his stores of arcane knowledge and ability. For these Heretics, an army of followers offer more direct solutions to obtain hidden knowledge - and protection from others who might seek to take the treasures that they have acquired. Sorcerers who follow this path often maintain a holding within the Screaming Vortex, where they can store their arcane resources and mentor their disciples. These rulers may then venture forth from their holdings to retrieve artefacts and components for their rituals that they undertake in the names of the Ruinous Powers.
