Passage 2:In 2003 they took a short break, during which McCaddon decided to leave Society's Finest, and went on to join Demon Hunter. After leaving Society's Finest and Embodyment, Ryan Clark and Don Clark, formerly of Training for Utopia, recruited him, Jesse Sprinkle, formerly of Poor Old Lu, and Jon Dunn (Who would later join Soul Embraced) to join their project, Demon Hunter. Demon Hunter already had an album before he joined. On this album McCaddon had contributed by photography. On his Demon Hunter debut, Summer of Darkness, was great success. In 2005, Ethan Luck, formerly of The O.C. Supertones and Project 86, replaced McCaddon. In 2006, former Embodyment members, Mark Garza (drums) and Andrew Godwin (guitar), contacted McCaddon and said they wanted to play metal again. McCaddon contacted former Society's Finest member, Nick Nowell (bass) and asked him to join their new project, The Famine. Though McCaddon knew people would compare the Famine to Embodyment, he stated that "We started The Famine because we wanted to get away from the stuff we were playing with Embodyment...".
