City of Heresy

Edward and Alphonse arrive at Liore, where they witness Father Cornello winning the devotion of the townspeople by performing "miraculous" transmutations, which they believe could only have been accomplished using a philosopher's stone. They meet Rosé and request to see Cornello, who is aware of the state alchemists' presence. Cornello ambushes Edward and Alphonse, sending a chimera, a human-animal hybrid, after them. While battling the chimera, Edward unintentionally reveals his prosthetic automail limbs, making Cornello realize that he had attempted the forbidden taboo of human transmutation. Edward and Alphonse escape, taking Rosé with them. While Alphonse explains their story to Rosé, Cornello finds Edward and reveals his nefarious plan, unaware that it had been broadcast to the whole town of Liore. Cornello uses the philosopher's stone on his ring to fight against Edward, but Edward manages to defeat him. Edward then realizes that the stone is a fake when it shatters on the ground. Cornello runs off, but is killed by Lust and eaten by Gluttony. When Rosé confronts Edward and Alphonse about the stone, despairing that she had believed in Cornello for nothing, Edward tells her to find strength within herself and to "walk on her own two feet."
