Two entities known as the Advancement (Lydia Grant) and the Reversion (Jonathan Carter) are the epitome of Good and Evil. Jon is banished to Earth and after a millennium and a half, he draws Lydia to him and tells her about a coming danger. Although neither knows it, the danger is their daughter, who both created them and is the only one who can destroy them. Can they find a way past their differences and stop her, or will all of creation be doomed to die?
