Curiosities of the Sacellum

Look at this wretched land, all forested and green, yet untouched by the Great Changer's hand. The flames of Change will soon sweep over this land and transform it in the Great Architect's image. One has not witnessed the Raven God's power until one has seen it in person. Do you wish to gaze into the eye of the Great Changer? Do you wish to feel Change wash upon your skin until corruption creeps out your throat? You hear the whispers upon the winds. He calls you. Heed his calling and venture to the Sacellum of the Inevitable City. It is there that true warriors are forged.

Speak to a flight master and travel to the Inevitable City. Once there find The Raven's Keeper in the Sacellum and learn about the Sacellum Holding Pits, where Chaos warriors are tossed for their initial trials.
