It was Callow, hideously transformed by Calatin for his part in the debacle that led to the freeing of the exiled Tuatha De Danann. His suffering had driven him insane and he had been stalking the Brothers and Sisters of Dragons as architects of his pain, cutting off fingers in a ritual that only he truly understood. He murdered Shavi with one blow of his knife, then loped away in pursuit of the others.

At Mam Tor, on the eve of Lughnasadh, the Fomorii attacked in force. Church sent Laura to stand guard over Ruth in the cottage while he faced up to Calatin in a mirror image of the confrontation on Skye that had led to his death. Although badly injured, this time Church had an advantage: the black sword bequeathed him by Mollecht. It had a life of its own, shaping his attack, then plunging into Calatin's heart of its own volition. Calatin was eradicated on the spot, a fate beyond imagining for a god unable to be completely destroyed. And then the sword revealed its true form: it was Mollecht's shape-shifting Caraprix.

Before the Fomorii could seek revenge, the Bone Inspector led Maponus into their midst, where the mad god wreaked vengeance for his suffering. When the carnage was finally over and the Fomorii fled, the Tuatha De Danann reclaimed their insane kinsman.

Then, in the middle of victory, there was only one last, terrible act for Church: to kill Ruth and prevent Balor from being reborn. As he approached the cottage with a heavy heart, Ruth stepped out, seemingly freed from the corruption of Balor. But nothing is ever that simple. Cernunnos had appeared during the battle and offered his potion to Laura, who accepted the sacrifice to save Ruth. The essence of Balor was transferred from Ruth to Laura, an act of spiritual redemption that would mean her own death. As Ruth gradually came round, Mollecht and his loyal Fomorii broke in and took Laura; the crowcreature's supremacy in the Fomorii hierarchy was now assured.
