After years of preparation, Guardian Lucas Sawyer was given his first assignment: protect the four angelic elementals and convince them to create the philosopher’ s stone. According to the prophecy left by medieval alchemist, Dr. John Dee, and the angels he communicated with, this generation of elementals would be the deadliest yet. Lucas had always feared them but when he met the Earth elemental, Vita, everything changed. He started to question the intentions of his leaders and the entire community of Elondoh. After uncovering impossible secrets left by John Dee, Lucas began to wonder who the real monsters were: the elementals or the humans sworn to protect them?
