Fly and his siblings captured a group of travelers and ate all but one before falling asleep. The man was able to escape, though he had no memory of anything before the incident. Josef met this man, and learned from him information about Thaegan's children for his book. 
Fly, Fie, and their nine surviving siblings—Hot, Tot, Zan, Zod, Pik, Snik, Lun, Lod, and Ichabod—join forces to seek vengeance on Lief, Barda, and Jasmine for the deaths of their mother ad siblings. As wolves, they pursued the companions and caught them in a net trap. Lief tricked them into fighting one another over how to equally divide the three people among eleven monsters. The fighting became lethal, and Fly and all his siblings died, except for Ichabod.
