Sanctify

In our very midst there is a breeding pit for the foulest and most corrupted creatures in the enemy's arsenal. Minor daemons devoted to the Dark Gods spew forth from within the Temple of Tzeentch, defiling everything in their path! Many evil rituals went into setting the altars of that vile place. The cult's leader would have recited the litany of Truculence while sprinkling the stones with the blood of innocent children! If we are to stop them, we must strike at their source. Only once the heart of their leader has been purified by fire can the shrine be cleansed. We must sanctify their corrupt shrine in Sigmar's name!

Travel into Deathmire forest and search for the Shrine of Tzeentch. Find Shrinekeeper Behorst inside and kill him. Purify his black heart by placing it in the Flame of Change upon one of the black altars.
