On the Brink of Chaos

Did you see that?! A Griffon! This is a sign from Sigmar himself! He is with you! You are chosen! You are a champion of Sigmar! He works in mysterious ways, but if you are chosen by Sigmar himself, who am I to question? Venture into the pit of vipers that has become our holy temple. Purge it of the evil that inhabits it in this realm and the next. My protege Wilhelm must learn from you. This is a perfect opportunity to prove himself. I will send the best of my Warrior Priests; the most faithful amongst them who have stayed strong in the face of all the evil this world has to offer, even when the other leaders of our temple fell to darkness. Go then, |n, Chosen of Sigmar, and Wilhelm, champion of Reikland Monastery. Stamp out the evil!

Find your way into the Reikland Monastery. Fight your way through the alcoves and use the Wicked Effigy to summon the Daemon Prince Vhar'keth. Defeat him and then report back to Hartmann Gottschalk.
