Here, the thieves perform the Rite of the Broken Wing, a hideous mockery of the Rite of the Fetish Egg that connects the stolen and dying egg to the infant next to it. Completing this relatively simple ritual requires the Ritemaster it to shatter systematically every bone in the left wing of a captive bird. Although agents of the Wyrm can use any bird, most prefer to use a raven — or a captive Corax. If the Rite of the Broken Wing fails, the egg dissipates and the infant dies. If it succeeds, it binds the two together in a horrible imitation of what should happen to a young wereraven. The damage to the egg and the corrupt energies of Malfeas both serve to warp the final creature. The Corax call these cursed unfortunates Buzzards or Scabs.
