Secret of the Griffon

Praise Asuryan! I've heard that others have survived the Giriffon Gate, and even now try to reclaim it. The Druchii have comitted too many forces to securing the route into Ellyrion, so we must act smarter. First, I need you to head West and hunt down these three targets. They'll be significantly harder to kill than the ones you handled before, so be careful and take allies. Second, I need to call in a favor with one of the Empire's Commanders -- but to get his aid, he first asks that we send aid to Altdorf. Do this for me, and we may yet have hope of reclaiming the Griffon Gate. The path forward has never been clearer.

Head West into The Shadowlands and defeat the 3 Marked Hero Targets, then defeat Arch Lector Verrimus in Altdorf's Sigmar's Crypts Dungeon.
