Dragon spawn.
A tale of an alien species coming to Earth and convincing us that we are subjugating reptiles from our ancient ancestors. The story is about how they are the Descendants of reptiles and dinosaurs, something that we have proof of, and of dragons. This utilizes our understanding of science as well as our fear of Mythology to conquer us. The main characters find out that the so-called ancient reptiles where the descendants of these creatures but in reality these creatures are using our own fears and beliefs to conqueror us. There are three factions that are created because of the fear the Dragon Kin, the sympathizers, and the Rebellion. The dragon Kin believe that these creatures are the descendants of Mythology and are like gods. The sympathizers believe these creatures are subjugated by our ancestors and need to be freed. The Rebellion believe that this is a way for these creatures to conquer us. In the end these creatures are actually Universal conquerors that have used past and present understanding to gain either Godlike status, sympathy, or have used brutal force to conquer planets.
