The first act of the Anti-Heroes campaign follows the original party through the fallen city of Elturel, the wastelands of Avernus, the search for the Sword of Zariel, and the final effort to save Elturel from damnation.
This act establishes the party’s identity as Anti-Heroes: capable of saving a city and redeeming a fallen angel, but also willing to lie, bargain, use people, ignore suffering, and make ugly choices when survival is on the line.
