The first "sparks" in terms of inspiration for Custodian occurred while I was still working on The Apple Tree, which is currently finishing up its festival run. Additional sources of inspiration came from gaming in a medieval universe and a particular song lyric that stuck with me. The Apple Tree was a nostalgic, idealistic piece with an environmental message, uplifting but poignant. I think it was a natural evolution to use animated images to explore the dark side of human nature, more mature themes such as guilt, penance, self-loathing; the concept that everyone is fighting a battle about which no one may know.
