It was not that the existence of the Solars, and to a lesser extent the Lunars and the Sidereals, has been eradicated from history. Rather their earlier identity had been lost under a history of decadence and absolute power. No one even recognised the Solars as Solars anymore. The Zenith Caste had long since become tyrants, priests of a god in whose name they no longer spoke and whose power they only abused not carried out. The Twilight Caste, once great enlighteners and brilliant sorcerers, had turned into twisted experimenters pushing the boundaries of knowledge with no care for humanity or their own souls. Even the Solars had forgotten what they were. In ancient histories, old enough to become myths, great heroes called Lawgivers raised mankind to rule the world. In the third age of the Old Realm their epithet became replaced by one far more fitting given to them by their Dragon-Blooded underlings: Anathema. They were no longer recognisable as or knew that they used to be Sun-Kings. Instead they'd become living demons. Great mortals would be chosen by a corrupting force that would twist their souls as they power swelled to inhuman proportions making the as evil as they were almighty. It was in this atmosphere of tyrany and oppression that the five Dragon-Blooded who would become known as the Immaculate Dragons started to foment rebellion against them.
